What are Fibroblast Cells?

he pig genome is three times closer to our genome that that of mice. Take the example of cystic fibrosis, the introduction of the mutation responsible for the disease in mice has not shown the exact course of the disease however, recent reports show the successful recapitulation of the disease in pig models. As there is a similarity between the cardiovascular system, the gastrointestinal tract, and the pancreas between pigs and humans, research on diseases and toxicology can be carried out on these models  with Swine Fibroblast Cells (Walters et al, 2013).

Noninvasive Technique Reveals How Cells’ Gene Expression Changes Over Time - Technology Org

MIT researchers can now track a cell’s RNA expression to investigate long-term processes like cancer progression or embryonic development.

Sequencing all of the RNA in a cell can reveal a great deal of information about its function and what it is doing at a given time. However, the sequencing process destroys the cell, making it difficult to study ongoing changes in gene expression.

An alternative approach developed at MIT could enable researchers to track such changes over extended periods of time. The new method, which is based on a noninvasive imaging technique known as Raman spectroscopy, doesn’t harm cells and can be performed repeatedly.

Using this technique, the researchers showed that they could monitor embryonic stem cells as they differentiated into several other cell types over several days. This technique could enable studies of long-term cellular processes such as cancer progression or embryonic development, and one day might be used for diagnostics for cancer and other diseases.

“With Raman imaging you can measure many more time points, which may be important for studying cancer biology, developmental biology, and a number of degenerative diseases,” says Peter So, a professor of biological and mechanical engineering at MIT, director of MIT’s Laser Biomedical Research Center, and one of the authors of the paper.

Koseki Kobayashi-Kirschvink, a postdoc at MIT and the Broad Institute of Harvard and MIT, is the lead author of the study, which appears today in Nature Biotechnology. The paper’s senior authors are Tommaso Biancalani, a former Broad Institute scientist; Jian Shu, an assistant professor at Harvard Medical School and an associate member of the Broad Institute; and Aviv Regev, executive vice president at Genentech Research and Early Development, who is on leave from faculty positions at the Broad Institute and MIT’s Department of Biology.

Imaging gene expression

Raman spectroscopy is a noninvasive technique that reveals the chemical composition of tissues or cells by shining near-infrared or visible light on them. MIT’s Laser Biomedical Research Center has been working on biomedical Raman spectroscopy since 1985, and recently, So and others in the center have developed Raman spectroscopy-based techniques that could be used to diagnose breast cancer or measure blood glucose.

However, Raman spectroscopy on its own is not sensitive enough to detect signals as small as changes in the levels of individual RNA molecules. To measure RNA levels, scientists typically use a technique called single-cell RNA sequencing, which can reveal the genes that are active within different types of cells in a tissue sample.

In this project, the MIT team sought to combine the advantages of single-cell RNA sequencing and Raman spectroscopy by training a computational model to translate Raman signals into RNA expression states.

“RNA sequencing gives you extremely detailed information, but it’s destructive. Raman is noninvasive, but it doesn’t tell you anything about RNA. So, the idea of this project was to use machine learning to combine the strength of both modalities, thereby allowing you to understand the dynamics of gene expression profiles at the single cell level over time,” Kobayashi-Kirschvink says.

To generate data to train their model, the researchers treated mouse fibroblast cells, a type of skin cell, with factors that reprogram the cells to become pluripotent stem cells. During this process, cells can also transition into several other cell types, including neural and epithelial cells.

Using Raman spectroscopy, the researchers imaged the cells at 36 time points over 18 days as they differentiated. After each image was taken, the researchers analyzed each cell using single molecule fluorescence in situ hybridization (smFISH), which can be used to visualize specific RNA molecules within a cell. In this case, they looked for RNA molecules encoding nine different genes whose expression patterns vary between cell types.

This smFISH data can then act as a link between Raman imaging data and single-cell RNA sequencing data. To make that link, the researchers first trained a deep-learning model to predict the expression of those nine genes based on the Raman images obtained from those cells.

Then, they used a computational program called Tangram, previously developed at the Broad Institute, to link the smFISH gene expression patterns with entire genome profiles that they had obtained by performing single-cell RNA sequencing on the sample cells.

The researchers then combined those two computational models into one that they call Raman2RNA, which can predict individual cells’ entire genomic profiles based on Raman images of the cells.

Tracking cell differentiation

The researchers tested their Raman2RNA algorithm by tracking mouse embryonic stem cells as they differentiated into different cell types. They took Raman images of the cells four times a day for three days, and used their computational model to predict the corresponding RNA expression profiles of each cell, which they confirmed by comparing it to RNA sequencing measurements.

Using this approach, the researchers were able to observe the transitions that occurred in individual cells as they differentiated from embryonic stem cells into more mature cell types. They also showed that they could track the genomic changes that occur as mouse fibroblasts are reprogrammed into induced pluripotent stem cells, over a two-week period.

“It’s a demonstration that optical imaging gives additional information that allows you to directly track the lineage of the cells and the evolution of their transcription,” So says.

The researchers now plan to use this technique to study other types of cell populations that change over time, such as aging cells and cancerous cells. They are now working with cells grown in a lab dish, but in the future, they hope this approach could be developed as a potential diagnostic for use in patients.

“One of the biggest advantages of Raman is that it’s a label-free method. It’s a long way off, but there is potential for the human translation, which could not be done using the existing invasive techniques for measuring genomic profiles,” says Jeon Woong Kang, an MIT research scientist who is also an author of the study.

Odd question kind of related to another I asked but to what extent to the animutants know their own anatomy? I suppose it’s fairly obvious that they know their structural anatomy(I mean, they don’t NEED to know the exact shape of their skull but they can probably guess it looks approximately like the general shape of their head) but do they know enough to do basic “maintenance” on their own?

For example does Sun know that his ray is mostly soft tissue, so for it to heal properly it probably needs to be compressed, and either way it will probably get inflamed before it can heal properly? (On a side note, soft tissue actually has three basic phases of healing-Inflammation(which lasts a week at most) where it will likely swell or be itchy, Fibroblastic Repair(often the same time as inflammation and lasts maybe six weeks at most) which really just means the cells are setting up the structure to replace the soft tissue and bring it back to being functional, and finally the actual structure repair which can take weeks or years. That’s the one where sensory and function returns. Fascinating isn’t it?)

Do they know that the glams probably have different spines and pelvic bones from the daycare attendants (That sounds like a weird thing to say but the glams have tails and the DCA are intersex which usually results in an interesting bone structure. Google it if you feel like it, it’s rather interesting!) so if they broke a leg they’d probably have to treat it different? I don’t think their legs are ‘digitigrade’ but if they are that probably means their legs and hips are pretty different from the DCAs’.

Sorry long ask it just hit me that if they don’t know, they probably have several infections in their futures

Okay so, yes, to some extend, and the different hip structure is actually gonna be mentioned in tomorrows chapter, even Sun is aware of it :D

Though, they don't always know too deeply "why" things are like they are, and how they should be treated in a case of emergency.

Sunrise for example wasn't even completely sure how his genitals worked... for other purposes than just peeing XD ofc it was partially just him being him.

I am not completely sure how certain injuries heal, like if the ray heals differently from other soft tissues because it's kinda hard to compare it to any human body parts, since I don't think it has bones in it, but might be closer to human ear cartilage, yet have some sort of muscle in it since they move.

I think swelling is gonna be the next part of the healing process, but as seen from Solar, the scars will most likely never completely fade.

Protective Partnership

If a house on your street was attacked, would you join forces with your neighbours to repair the damage and fend off the intruders? That, it seems, is what two cell types in your gut do. The intestine lining faces a constant barrage of physical forces and biological material, so regular maintenance and repairs are essential. Researchers investigating this regulation, and how inflammatory bowel diseases such as colitis arise when it goes wrong, looked at the role of interleukin-11, a product of the immune system. Without it, colitis in mice worsened and more cells of the gut lining died. Interleukin-11 (green, present in damaged areas of tissue) is produced by connective cells called fibroblasts, but the researchers found that other immune cells also regulate its levels by releasing highly reactive molecules. Interleukin-11 protects the lining during inflammation, and the collaboration that produces it must be considered in any potential treatments.

What makes Centella Asiatica such a hot skincare ingredient?

Centella Asiatica belongs to the genus Centella in the umbelliferous family, also known as gotu kola or Indian pennywort. Centella Asiatica has the function of clearing heat and detoxifying, clearing swelling and dehumidifying. Centella Asiatica was used as a traditional medicine to treat injuries of beating and skin diseases for thousands of years. How is it used in skin care products? Why Centella Asiatica is such a popular skin care ingredient? Let's explore together. In recent years, scientists found that Centella Asiatica Extract can stimulate the proliferation of skin fibroblasts and regulate the disordered proliferation of fibers. It also promotes scar repair, reduces pigmentation, promotes protein regeneration, and restores skin elasticity and shine. At the same time, it also has antioxidant, anti-aging, anti-inflammatory magic effect.These characteristics laid the foundation for it to become a hot ingredient in the skin care field.

The star ingredient of antioxidants

Centella Asiatica contains triterpenoids, which are known to have antioxidant properties. Its antioxidant properties inhibit free radical activity and help protect the skin from free radical damage. Free radicals are unstable molecules that are produced by a variety of factors, including pollution, ultraviolet radiation and cigarette smoke. When free radicals attack the skin, they can cause wrinkles, age spots and other signs of aging. Centella Asiatica is rich in antioxidants such as flavonoids, triterpenes, phenolic acids and Centella Asiatica glycosides, which help neutralize free radicals and protect skin from damage. At the same time, it can reduce the production of dark spots, improve the skin blood circulation, renew the skin cell regeneration, and brighten the skin.

Powerful anti-inflammatory soothing repair action

Centella Asiatica is known for its anti-inflammatory, soothing and repairing properties. Inflammation is the body's natural response to injury or infection, but chronic inflammation can cause damage to the skin and lead to premature aging. Inflammation is caused by a variety of factors, such as pollution, ultraviolet radiation and stress. When the skin becomes inflamed, it becomes red, swollen and painful. Triterpene compounds found in Centella Asiatica extract have been shown to have anti-inflammatory effects on the skin. These compounds reduce inflammation and redness, soothing and repairing skin. These properties make Centella Asiatica extract an excellent ingredient in skin care products for people with sensitive skin or acne skin.

Excellent choice against early aging

Centella Asiatica promotes collagen synthesis and mucoglycan secretion, both of which make it an excellent ingredient in anti-aging skin care products. Collagen is a protein that gives skin its structure and elasticity. As we age, the production of natural collagen in our skin slows down and collagen levels decline, which can lead to wrinkles and sagging skin. Centella Asiatica has been found to stimulate collagen synthesis, helping to improve skin firmness and elasticity, and adjusting the overall texture and tone of the skin. The secretion of mucosaccharide can promote skin hydration and increase skin elasticity, enhance the vitality of the underlying cells of the skin, maintain skin elasticity and firmness, and smooth the fine wrinkles of the face.

A powerful moisturizer for the skin

Centella Asiatica has a moisturizing effect, which improves skin hydration. Water is necessary to keep your skin healthy, and keeping it moist is essential to keep it healthy. When skin is dry, it becomes itchy, flaky and dull. Centella Asiatica contains compounds called saponins that help increase the production of hyaluronic acid, a molecule necessary for skin hydration. When skin is hydrated enough, fine lines and wrinkles are smoothed out, leaving skin looking fuller and younger.

What skin type is suitable for skin care products containing Centella Asiatica?

Centella Asiatica is a powerful skincare ingredient that offers a range of benefits for the skin. This ingredient can be used in combination with all skin types, especially the following three skin types. Acne skin: often burst acne or stubborn acne mark skin type, can be used with Centella Asiatica ingredients for scar to remove acne mark, promote wound healing.

What skin type is suitable for skin care products containing Centella Asiatica?

Lilac update

Vet called back with the cytology results (very fast tbh!). Results are.... not as conclusive as I’d like!! Lots of inflammatory cells, which does suggest a granuloma, aka infection. But also a number of fibroblasts (connective tissue cells) which means they can’t rule out tumor. Seems like we’re leaning toward infection for now, particularly bc that’s the one that’s treatable.

He’s concerned about it being mycobacterium but I’m doubtful. It doesn’t seem severe enough for that, and nothing new has been introduced to the tank in years save for the limpets a few weeks ago, and I guess those basil cuttings I was sprouting in the fall? But that lump has been there a loooong time.

I’m way more suspicious of it being related to that Mystery Disease from a couple years back... The one that wiped a good third of my tank. At one point I thought Lilac had it, enough that I quarantined her, but she never developed the rest of the symptoms, or well, died horribly. In spite of working with another vet and getting several necropsies and samplings done I never found out what that pathogen was. The pathologist working on it did definitively say that he did NOT find mycobacterium. But given that it’s unknown, who knows if maybe she was infected after all but has been surviving somehow, with this growing granuloma to show for it. Two of the necropsies did find granulomas in multiple organs, although I guess maybe that’s not a super specific symptom...? At one point the disease did disappear for a while only to crop up again several months later and kill another fish so I do think there can be some kind of latent infection. Idk. I’m going to ask about it.

I have to bring her back in today anyway. It’s antibiotic day but the syringes they gave me don’t have markings small enough to measure out the absolutely TINY dose I need to give her so I’m just gonna bring her there for the doc to do it, and pick up some smaller ones maybe. If I have time I’ll talk to him about the Mystery Disease but I know he’s fitting me at the end of the work day when they’re closing so I don’t wanna hold him too long.

Also, she’s still wiggly and eating which is good. I may add a bit of salt since her fins and slime coat are a little roughed up from being on her side so long. Maybe pick up some api slime coat too. She’s such a good girl 🥺

hey ehlers danlos people

has anyone had increased symptoms with anticholinergic meds? not just from muscle relaxant issues, that’s a known thing, but from merely taking such medication itself.

there’s a research paper from 2008 i found that says anticholinergics can greatly weaken collagen in pathogenic lung tissue found in asthmatics. specifically: “In human lung fibroblasts, muscarinic receptors exert stimulatory effects on collagen synthesis. Prolonged blockade of muscarinic-induced collagen synthesis may contribute to reported beneficial long-term effects of anticholinergics in chronic obstructive pulmonary disease.”

AKA, it’s possible that interference from anticholinergics can make collagen weaker, which would mean you get more eds symptoms. the paper isn’t proof that this is a real thing throughout the body, it’s evidence that it does exist in some pathogenic tissue; it may happen in all tissue.

following that paper, in 2013 there’s another citing the 2008 paper which found that “Human tenocytes are stimulated to proliferate by acetylcholine through an EGFR signalling pathway”, which means that “stem cell” tendon tissue responsible for making regular tendon tissue gets instructions to do that via acetylcholine. anticholinergic drugs block acetylcholine, which means tenocytes get less stimulation to produce new material, so old collagen doesn’t get replaced like it should. assuming this extends to all collagen production and not just tendon tissue, this is more evidence that anticholinergic drugs can interfere with the production of collagen.

following that paper, in 2016 another paper looked at the effect of knocking out an acetylcholine receptor on arthritis: “Taken together, the present study shows that while M3R−/− mice [the ones with the deleted receptor] were not protected from CAIA [induced arthritis], they had a tendency toward a higher inflammatory response after arthritis induction than WT mice [normal mice]. Further, arthritis-induced joint destruction was significantly stronger in mice with M3R deficiency, indicating that stimulation of M3R might have protective effects on arthritis.” More or less this seems to mean that when the action of acetylcholine is blocked, which is what happens when you kill the receptor and when you block it with anticholinergic drugs, the joint tissue is worse off and more inflamed than it otherwise would be. Acetlycholine appears to be necessary for healthy tissue.

in healthy people this may not cause any problems, but in people with eds who have a preexisting synthesis and weakness issue, it could drastically compound the existing problems, or even incite symptoms that didn’t previously exist, as was found in that last arthritis paper. as far as i’m aware, we don’t actually know the mechanism of why collagen is weaker in eds; it’s possible that acetylcholine differences could be a reason, and if they are, then drugs that block the action of that would naturally make the problem worse. i’m not saying this is definitely happening, but my own eds issues happened severely out of nowhere after not existing when i started anticholinergic drugs, and such medications have recently been found to cause wildly negative damage, like permanently raising your risk of death and shortening your lifespan.

anyhow, point is, i would like to know if anyone has had increased problems when they took anticholinergic meds, that aren’t due to muscle relaxant effects. anticholinergics can be things like benadryl, most psychiatric drugs, muscle relaxers, and other medications that are listed as “low effect” but are dose-dependent, such as all the third generation antihistamines and the h2 blockers.

i suppose this applies to all collagen disorders, not just eds

What is an exosome treatment?

An introduction to exosome therapy

Have you heard about the potential of exosomes for treating various diseases but aren't quite sure what exosomes are or how exosome therapy works? You're not alone. Exosomes are tiny vesicles released by stem cells and other cell types that have immense therapeutic potential but remain relatively unknown to most people.

In this comprehensive guide, we'll discuss what exosomes are, how they function within our bodies, the process of isolating and utilizing exosomes for medical applications, current research on exosome therapy, and potential future applications. By the end, you'll have a solid understanding of this emerging field of regenerative medicine.

What are exosomes?

To start, let's define exosomes and explore their basic structure and function. Exosomes are tiny membrane-bound sacs or vesicles ranging from 30-150 nanometers in diameter released by cells as a means of intercellular communication. All cells produce exosomes, including stem cells, immune cells, and cancer cells.

Exosomes contain cargo in the form of proteins, lipids, mRNAs, microRNAs, and other molecules transferred to neighboring cells or cells in other parts of the body. This protein and nucleic acid cargo depends on the originating cell type and can convey messages that alter the behavior and function of recipient cells. For example, exosomes from stem cells have been found to enhance tissue regeneration.

Exosomes originate within cells via the endosomal pathway. Early endosomes within cells fuse to form late endosomes called multivesicular bodies (MVBs). As MVBs fuse with the cell membrane and are released into the extracellular space, they are called exosomes due to their external origin. MVBs can either fuse with lysosomes for degradation or fuse with the cell membrane to release exosome contents.

The lipid bilayer membrane of exosomes protects the cargo from degradation and allows it to travel distances within the body. Exosomes derived from stem cells have been shown to survive for extended periods after administration and target multiple tissues. Due to their small size, exosomes can bypass biological filters to reach sequestered areas of the body not accessible by larger particles.

How do exosomes function and communicate between cells?

We've established that exosomes transport cargo between cells, but how exactly does this intercellular communication occur? Let's explore the multi-step process through which exosomes influence distant cell populations.

First, exosomes must bind and fuse with target cells. They achieve this through interaction between molecules displayed on their membrane surface and target cell surface receptors. For example, fibroblast growth factors and epidermal growth factors on the exosome surface may bind receptors on recipient cells.

Once fused, exosome contents are released into the cytoplasm or nucleus of target cells. The specific proteins, lipids, mRNA, and microRNA cargo can then orchestrate dynamic changes in target cell behavior and function. Proteins may activate intracellular signaling pathways while mRNA and microRNA may regulate gene expression by silencing target genes.

Some key effects observed across research include increased cell proliferation, altered metabolism, stimulated angiogenesis, suppressed apoptosis or cell death, enhanced migration, and pro- or anti-inflammatory signaling. These changes can prime target cells to undergo phenotypic switching or differentiation into alternate specialized cell types.

Ongoing research continues to unravel the complex communication between exosomes and recipient cells. Exosomes serve as messengers that shape biological responses in distant tissues. This intercellular network allows one cell to participate remotely in physiological and pathological processes occurring at other sites.

Sources and isolation of exosomes

Now that we understand what exosomes are and how they convey molecular information, let's explore their sources and medical applications through exosome isolation from regenerative cell types. Exosomes have been identified in nearly all body fluids, including blood, urine, saliva, amniotic fluid, breast milk, and more. However, stem cell-derived exosomes have emerged as a promising area of research due to their natural reparative abilities.

Some key stem cell sources of exosomes explored in research include:

Mesenchymal stem cells (MSCs) are obtained from bone marrow, adipose tissue, and tissues associated with organs like the heart, kidney, liver, etc.

Umbilical cord perivascular cells - These are stem cells from umbilical cord tissue surrounding blood vessels.

Adipose-derived stem cells - Stem cells derived from human adipose or fat tissue via liposuction.

Placental cells - Stem cells isolated from the placenta after birth provide a noncontroversial stem cell source.

Once stem cells are cultured in the lab, the conditioned medium containing stem cell-derived exosomes must be isolated. Several separation and ultracentrifugation protocols are followed to obtain a purified exosome fraction. Characterization is then done using techniques like transmission electron microscopy, nanoparticle tracking, and Western blotting to confirm the presence of specific exosomal markers like CD63, CD9, and CD81.

Research has demonstrated that the cell of origin influences the protein and genetic content within each exosome population. MSC exosomes have displayed immunomodulatory, antioxidative, and pro-regenerative activity across preclinical experiments. Much effort is underway to isolate exosomes from available cells using gentle, standardized protocols to minimize contamination and preserve bioactivity.

Mechanisms of action

Now that we've covered isolation, let's discuss how exactly exosomes exert their therapeutic benefits based on findings from foundational research. One of the primary mechanisms involves exosomes' ability to promote cellular migration, angiogenesis, and tissue regeneration by modifying gene expression profiles in recipient cells.

Using their miRNA, mRNA, and protein cargo, exosomes can influence intracellular signaling pathways and genetic programs associated with inflammation, cell proliferation, apoptosis, hypoxia responses, and differentiation. This allows MSC exosomes to suppress fibrosis, modify the immune response away from Th1/Th2 dominance, and stimulate constructive tissue remodeling.

Much research indicates that the mechanisms of action are context-dependent, varying based on the target tissue, manner of administration, and cell source. To summarize some key effects observed:

Anti-scarring – Reduced fibrosis and scar tissue formation in skin, liver, lung, and kidney

Angiogenesis – Stimulated new blood vessel growth through angiogenesis promotion

Immunomodulation – Redirected inflammation towards a healing response

Cell migration – Stimulation of endogenous stem and regenerative cell homing

Neuroprotection – Supported neural stem cell survival and differentiation

Tissue protection – Anti-apoptotic, antioxidative repair of damage

Matrix turnover – Altered tissue matrix composition for remodeling

Epithelial wound healing – Accelerated re-epithelialization of ulcers/injuries

Anti-microbial – Boosted defense against biofilms and microbial pathogens

This diversity allows the application of exosome therapy in diseases affecting multiple systems and demonstrates their multi-target therapeutic capabilities.

Application and advantages of exosomes

Having explored how exosomes operate, we can now discuss their significant advantages driving investigation as a new class of biologic therapy. Exosome therapy offers a cell-free, non-controversial alternative to stem cell therapy devoid of many limitations like poor engraftment, short lifespan, and potential tumorigenicity.

Here are some key advantages of exosome-based treatments:

Abundance and stability - Exosomes maintain function for extended periods in biofluids and can be stored at scale.

Precision targeting - Unique membrane proteins allow homing of exosomes to specific organ/tissue types.

Multi-targeting - Single exosome therapy can impact multiple cell/tissue networks via diverse cargo.

Ease of administration - Administered systematically or locally through approved routes like injections or topical gels.

Elimination of teratoma risk - The absence of whole stem cells prevents tumor/teratoma formation post-therapy.

Improved safety - No long-term cell survival or immunological rejection concerns after therapy.

Personalization - Exosomes from autologous sources avoid immunological barriers to acceptance.

Scalable production - Produced from accessible stem cell sources easily multiplied in culture.

Natural healing signals - More physiological approach transmitting native intercellular messages.

These advantages have allowed the evaluation of exosome therapies in areas including wound healing, cardiovascular disease, graft versus host disease, infertility, neurodegenerative disorders, and cancer.

To dive deeper into a specific application, let's explore ongoing research using adipose-derived exosomes (ADEs) from stem cell sources for skin rejuvenation:

Case study: ADEs for skin rejuvenation

Researchers from the r3stemcell clinic in California have studied the potential of adipose-derived exosomes (ADEs) sourced from adipose stem cells isolated through liposuction for aesthetic applications in skin rejuvenation. ADEs have displayed regenerative properties through the secretion of growth factors, cytokines, microRNAs, mRNAs, and proteins with wound healing, anti-scarring, and anti-aging effects.

In preclinical models, topical or subcutaneous administration of ADEs enhanced collagen production, reduced inflammation and stimulated healthier granulation tissue formation and vascularization compared to non-treated models. The secretory factors TGFβ1, FGF, VEGF, and others likely drive this remodeling. ADEs also displayed significant antioxidant activity in repairing free radical-induced skin cell damage.

Based on these mechanistic findings, r3stemcell launched clinical trials involving subcutaneous injections of ADEs in combination with platelet-rich plasma for facial rejuvenation applications. Preliminary findings displayed improvements in skin texture and tone, reduction of wrinkles and folds, and enhanced support for volume retention. Patients saw improvements lasting up to 6 months with additional therapies.

Ongoing monitoring found no major adverse reactions or safety concerns related to ADE therapy. However, they note larger studies are still needed with controls and long-term follow-up periods before definitive conclusions can be drawn on efficacy for this application.

Overall, the capability of ADEs to stimulate chronological aging-like changes in skin renews interest in their potential as an approach for aesthetic rejuvenation. Further investigation may optimize dose, regimen, and administration routes. Their non-invasive mechanism and established safety profile also warrant continued study of ADE treatment potential for aging, acne scarring, and other skin conditions.

Research status and future potential

Experimental studies support the benefits of exosome therapy across a wide range of disease states, from inflammatory and immune disorders to ischemia-reperfusion injuries, fibrosis, trauma, neurodegeneration, and even wound healing in diabetic conditions normally resistant to repair.

However, this research remains in clinical trial stages for most applications due to several information gaps limiting the transition of exosome technology. These include optimization of isolation, characterization techniques, defining appropriate quality controls, scaling production processes, standardizing administration routes, and elucidating mechanisms at molecular levels.

Large placebo-controlled clinical trials with follow-up periods extending years are also still required to firmly establish clinical efficacy versus traditional therapies and certify long-term safety profiles. Few exosome therapies have achieved regulatory approval so far beyond a few small trials.

Nevertheless, important milestones toward medical use continue to be attained. Production processes have scaled to generate billions of exosomes while retaining bioactivity. Emerging technologies now promise point-of-care isolation directly from biofluids. FDA approvals for early-phase trials increase steadily across conditions.

The coming years should reveal whether exosome therapy delivers on its promise as a cell-free revolution in personalized regenerative medicine. Exciting future directions involve engineering exosomes as precision drug delivery vehicles for target tissues, engineering the ability for sustained or triggered release of payloads, and optimized production from induced pluripotent stem cells for autologous "off the shelf" therapies without tissue matching barriers.

If safety and large efficacy studies succeed, exosomes may transform the treatment landscape across chronic conditions currently facing inadequate therapeutic options or rescue of failing organs through remote tissue regeneration abilities. Convenient storage and targeted administration could establish exosome therapies globally as widespread clinical tools.

In any case, the ability of exosomes to transmit sophisticated intercellular communication messages between locations offers tremendous insight applicable to understanding development, disease mechanisms, and aging itself while driving the next wave of cellular therapies. Continued investigation continues apace to unravel their full potential.

Conclusion

In this extensive guide, we have delved into the exciting field of exosome therapy by exploring what exosomes are, how they originate and operate within our bodies, current isolation techniques and research progress, key applications under study, advantages over traditional therapies, remaining challenges, and promising future directions.

By disseminating complex molecular cargoes over distances, exosomes empower one cell population to influence or program the biology of another in a minimally invasive, cell-free approach. Their natural regenerative motifs align well with an increasing focus on physiological healing signals over synthetic interventions.

If studies can demonstrate exosome therapies as broadly effective and safe alternatives, their application across inflammatory, autoimmune, degenerative, and other therapeutic resistance conditions may reduce the societal burden of chronic disease globally. Their non-immunogenic abilities could also transform fields like transplantation and gene therapy.

Our growing understanding of exosome-mediated intercellular communication also widens comprehension of development and pathology on systemic levels while providing novel biomarker and therapeutic targeting avenues. Continued research efforts remain key to establishing their medical benefit as a cell-free solution poised to elevate regenerative medicine.

What Is SkinSeqnc, and How Does It Work?

SkinSeqnc is a leading Canadian company that uses free-cell technology to make advanced skin care products that nourish and rejuvenate the skin. These products are made from human mesenchymal stem cells (MSCs) that come from carefully sourced human umbilical cord lining (hUC-MSCs). You have come to the right place to buy SkinSeqnc online if you want to be the first to offer this cutting edge skin care technology to your patients. MSCs give SkinSeqnc goods their power. Due to their cells' ability to change into any other type of cell, including skin cells, they are known for their ability to grow back. MSCs can be gotten from bone marrow and adipose tissue, but the best place to get them is from the lining of the umbilical cord (hUC-MSC). That's why the company only uses hUC-MSC that was obtained in a safe way. Plant and animal stem cells can be used, but they aren't as useful and come with more risks of spreading pathogens and other problems. Many research papers have shown that hUC-MSCs have the amazing ability to help new cells grow, especially fibroblasts, which helps skin tissue repair. Because of this, the body makes more collagen and elastin, which makes the face feel and look better overall. The hardest part is getting stem cells to the patient without any bad affects. This is where the free-cell technology from SkinSeqnc (a manufacturer) comes in. A liquid solution is used to grow the stem cells. They produce growth factors, proteins, and other molecules during the process, making a complex mix of biomolecules. Then, this mixture is mixed with other things to make great anti-aging items that people can use.

Crash Course: Anatomy & Physiology - Types of Connective Tissues

Summary:

Loose and Dense Connective Tissue

Areolar, Adipose, Reticular, Tendons, Ligaments, Dense Irregular and Dense Elastic Tissue

Three Cartilage Types: Spongy and Compact Bone Connective Tissue

Blood is Connective Tissue Type

"No matter how different a tendon, bone or hunk of fat may appear, they are indeed very closely related."

All spring from the same embryonic cells, and their structures are dominated, not by cells, but by an extracurricular matrix full of fibers.

Connective Tissues

Proper

Cartilage

Bone

Blood

Loose vs Dense Connective Tissue Proper

Connective Tissue Proper

based on how many fibers it has in its ground substance

Loose

areolar

reticular

adipose

Loose connective tissue have fewer fibers, more cells and more ground substance.

Dense

regular

irregular

elastic

Tendons are an example of dense connective tissue.

Types of Loose Tissue Proper: Areolar, Adipose and Reticular

Areolar Tissue

fibroblast cells

elastic fibers

collagen fibers

Areolar tissue is the most common loose connective tissue, found all of your body, just under the epithelial tissue, and wrapped around organs.

It has a loose and random arrangement of fibers, with a few fibroblast cells that make the fibers.

Latin term - "a small open space"

E.g. If you slam your shin on a coffee table and inflame the area, the areolar tissue soaks up extra fluids like a sponge, and resulting swelling and puffiness is called edema.

Areolar tissue is a kind of sponge for watery ground substance.

Adipose Tissue (Fat Tissue)

adipocytes

nucleus

lipid vacuole

Adipose tissue is mostly cells, adipocytes, which store lipids for later use, insulate the body against heat loss and grow pot bellies/love handles.

The average person's weight is 18% adipose tissue.

Reticular Tissue

reticular fibers

developing blood cells

Reticular tissue is similar to areolar tissue, but with a woven mass of reticular fibers, instead of collagen and elastin fibers.

It provides the soft internal framework, or stroma, of the spleen, lymph nodes, and bone marrow, and supports lots of developing bloody cells.

While areolar tissue is a kind of sponge for watery ground substance, reticular tissue is what holds your blood in place in many of your organs.

Loose connective tissue proper types share an airy dispersal of fibers.

Types of Dense Tissue Proper: Regular, Irregular and Elastic

Dense Regular Tissue

fibroblast nucleus

collagen fibers

Dense regular tissue is full of tight bundles of collagen fibers all running parallel.

Found in tendons, muscle to bone, and ligaments, which bind bones together anywhere there's a joint

Dense Irregular Tissue

collagen fibers

fibroblasts

Dense irregular tissue, whose fibers are thicker and arranged erratically, are found wherever tension may be exerted in lots of different directions. E.g. the leathery dermis underlying skin

Dense Elastic Tissue

elastic fibers

stretchy, elastic tissue

Found in vertebrae, so spine can curve and twist.

Found in large artery walls, provides support and flexibility.

Connective tissue proper is the most diverse group in this tissue family.

Types of Cartilage: Hyaline, Elastic and Fibro

Cartilage

Cartilage doesn't have any blood or nerves and stands up against both tension and compression pretty well.

Hyaline

chondrocytes

lacunae

Hyaline cartilage is the most common type.

glassing-looking, provides pliable support

It connects ribs to the sternum and keeps the tip of the nose perky.

Its ground substance is rich with sticky, starchy proteoglycans.

Although it has collagen fibers, you can't really see them under a microscope, instead the tissue looks glass.

"Hyal" = glassy, transparent.

Elastic Cartilage

chondrocytes

elastic fibers

Elastic cartilage is similar to hyaline cartilage, but with more elastic fibers that are easier to see.

Found in places where strength and stretchability are needed.

Fibro Cartilage

chondrocyte

collagen fibers

Fibro cartilage acts as a shock absorber. It's dominated by thick fibers of collagen and is good at withstanding pressure, so it makes up the discs between vertebrae, and knee joints where it keeps bones from grinding together.

Types of Osseous (Bone) Tissue: Spongy and Compact

Fun Fact: Each bone is considered a separate organ

"Bone" can refer to an entire organ, like femur or scapula, or just bone tissue.

Bone, or osseous tissue, is calcified connective tissue, perfect for supporting and layering the body's various structures.

Spongy Bone Tissue

Spongy bone tissue is typically found in the heads of long bones and in the inner layer of flat bones. E.g. sternum.

It's strong, but porous, even to the naked eye, and uses the extra room to make and store bone marrow.

Compact Bone Tissue

osteocyte (within lacuna)

Compact bone tissue is quite dense, with no visible spaces. It forms the external layer of the bones and stores calcium for bone cells to use to make more tissue

Blood is a Connective Tissue

connects distant parts of your body

provides rigidity to other parts

Blood develops from mesenchyme, is made up of cells surrounded by an extracellular nonliving matrix.

The ground substance is the blood plasma, which has protein fibers floating around it.

The blood's main job is delivery - transports cells, nutrients, hormones wastes etc., keeping all the parts of the body connected in the process.

Blood

Red Blood Cells

Erythrocytes

Zoom around, carrying oxygen and carbon dioxide through the body.

White Blood Cells

Leukocytes

larger

infection-fighting

Platelets

The small cell fragments needed for blood cutting.

Unlike other connective tissues, it doesn't have typical fibers, but instead has protein dissolved in the plasma, and the protein molecules form fiber-like structures when blood needs to clot.

Make sure to let the skin sleep

Long term exposure to sunlight and staying up late can lead to collagen loss and poor skin condition. It seems like common sense already.

If there is no sun protection, can supplementing collagen peptides repair the skin damage caused by staying up late?

I haven't stayed up late or been exposed to sunlight. Should I supplement my collagen peptide?

In today's article, we will delve deeper into the connection between sun exposure, staying up late, and collagen, revealing another layer of truth behind skin aging.

Why does photoaging lead to collagen loss?

Collagen and elastin are structural proteins in mammalian connective tissue that play a role similar to plant cell walls, respectively endowing tissues with mechanical strength and elasticity.

Meanwhile, collagen loss is also an important marker of skin aging.

As age increases, as well as the effects of environmental factors such as UV light, trauma, and mechanical stress, collagen will gradually be lost, causing the skin to lose its original appearance.

We refer to endogenous aging caused by aging as natural aging, and exogenous aging caused by environmental factors such as ultraviolet light exposure as photoaging.

In this article, we mainly introduce the latter.

Why does photoaging occur?

A study from South Korea detailed the skin condition under different age groups and UV light conditions:

This study used newborn baby skin, elderly frontal skin, and abdominal skin for in vitro cultivation of fibroblast cell lines (frontal skin exposed to sunlight for a long time, while abdominal skin showed almost no photoaging).

As shown in the figure, in the collagen gel and monolayer culture containing 1% fetal bovine serum (FCS), compared with neonatal fibroblasts, the percentage of collagen synthesized by fibroblasts in the abdomen and forehead of the elderly was significantly reduced.

In collagen gel and monolayer cultures containing 1% FCS, compared with abdominal skin fibroblasts from the same elderly individuals, the relative level of collagen synthesis of fibroblasts cultured from frontal skin was significantly increased.

Therefore, we can draw two conclusions:

Aging of individuals can lead to a decrease in skin collagen synthesis levels, which may lead to skin aging.

Long term sunlight exposure can lead to an increase in skin collagen synthesis levels and may also lead to skin aging.

This seems to be a contradictory conclusion - we all know that a lack of collagen can lead to skin damage, and supplementing collagen is beneficial for the skin.

But the experimental results say that ultraviolet light, which causes skin aging, increases collagen protein. What exactly is going on?

The following study may explain this issue.

UV rays accelerate collagen breakdown

This paper aims to explore the histological changes of photoaging skin and directly conducts biopsies on human skin.

Compared to in vitro culture experiments, in vivo tissue biopsy is often more convincing:

Researchers examined the content and distribution of collagen in human skin damaged by sunlight.

The result shows:

In photoaging skin, each milligram of total protein contains 524 micrograms of collagen;

In non sun exposed skin, each milligram of total protein contains 667 micrograms of collagen.

The total collagen content of photoaging skin is about 20% lower than that of non sunburned skin.

It is speculated that this is due to the significant increase in the decomposition rate of collagen under ultraviolet light.

This also explains why collagen synthesis increased while the total amount decreased.

In addition, the experiment also revealed another molecular mechanism of skin photoaging, namely the disorder of collagen structure:

Researchers compared the molecular composition of collagen in two types of skin tissues and found that:

Compared to skin not exposed to sunlight, the content of the complete N-terminal prepeptide portion of type III collagen in sunburned skin decreased by 40%.

→ Core principle: UV radiation leads to a decrease in N-terminal prepeptides

To clarify this issue, we need to start with how collagen is synthesized:

As shown in the figure below, monomeric collagen, also known as procollagen, is composed of three polypeptide chains（ α Chains are formed by folding each other.

Numerous collagen fibers are connected to each other through cysteine residues on them, forming a well-organized collagen fiber structure.

Newborn within cells α On the chain, there is not only the structural sequence of collagen protein, but also a functional sequence that plays an auxiliary role at both ends, called the C (carboxyl) terminal prepeptide and N (amino) terminal prepeptide.

The C-terminal prepreptide is responsible for binding three α The chains are cross-linked with each other, and the N-terminal peptide is responsible for the formation of its helical structure.

After completing their respective tasks, they will be cleaved by hydrolytic enzymes and enter the bloodstream, ultimately being metabolized by the liver.

Therefore, their concentration in the blood also reflects the synthesis of collagen.

In clinical medicine, abnormal concentrations of N-terminal and C-terminal peptides in the blood are considered important indicators for many disease examinations.

N-terminal prepreptide damage, α Chains cannot be twisted normally to form spiral shaped collagen with complete structure and function, and the collagen fibers constructed by these "unqualified" collagen will inevitably have defects.

This means that even if the collagen content is sufficient, there is still a possibility of abnormal skin function due to differences in its "quality".

Unveiling the Power of Anti-Aging Peptides for Youthful Skin

Introduction

In the realm of skincare, the pursuit of youthful, radiant skin is a timeless quest. From ancient remedies to modern scientific breakthroughs, humans have continuously sought ways to defy the visible signs of aging. Among the latest innovations gaining traction in the beauty industry are Anti-Aging Peptides — tiny yet mighty molecules with the potential to revolutionize skincare routines. Let’s delve into the science behind peptides and discover how they unlock the secret to youthful skin.

Understanding Peptides

Peptides are short chains of amino acids, the building blocks of proteins, which play a fundamental role in various biological functions. In the context of skincare, Anti-Aging Peptides function as messengers, signaling cells to perform specific tasks such as collagen production, wound healing, and tissue repair. When applied topically, peptides penetrate the skin and communicate with cells, prompting them to revitalize and rejuvenate.

Collagen Boosting Properties

One of the most significant benefits of peptides is their ability to stimulate collagen production. Collagen is a protein responsible for maintaining the skin’s firmness, elasticity, and youthful appearance. As we age, collagen production declines, leading to the formation of wrinkles, fine lines, and sagging skin. Peptides work by signaling fibroblast cells to produce more collagen, thereby restoring the skin’s structure and improving its overall texture and tone.

Targeted Solutions for Aging Concerns

What sets peptides apart is their versatility and specificity. Different types of peptides target distinct skin concerns, allowing for customized skincare solutions. For instance, some Anti-Aging Peptides focus on reducing the appearance of wrinkles by promoting collagen synthesis, while others target pigmentation issues or boost hydration levels. By incorporating peptides into skincare formulations, manufacturers can tailor products to address specific aging concerns effectively.

Antioxidant and Anti-inflammatory Properties

In addition to their collagen-boosting effects, peptides exhibit antioxidant and anti-inflammatory properties. Antioxidants help neutralize free radicals, harmful molecules that contribute to premature aging and skin damage. By scavenging free radicals, peptides protect the skin from environmental stressors such as UV radiation and pollution, helping to maintain its youthful vitality. Furthermore, peptides with anti-inflammatory properties soothe irritated skin, reducing redness, and promoting a calmer complexion.

Gentle and Safe for All Skin Types

One of the most appealing aspects of peptides is their gentle yet effective nature. Unlike some harsh anti-aging ingredients that can cause irritation or sensitivity, peptides are well-tolerated by most skin types, including sensitive skin. They offer a gentle alternative to invasive procedures or aggressive treatments, making them suitable for individuals seeking non-invasive solutions to aging skin concerns. Whether you have dry, oily, or combination skin, peptides can be incorporated into your skincare routine without fear of adverse reactions.

Incorporating Peptides into Your Skincare Routine

With the growing popularity of Anti-Aging Peptides in the beauty industry, an array of skincare products containing these potent molecules is now available. From serums and creams to masks and moisturizers, there are numerous options to choose from. When selecting peptide-infused products, look for formulations that contain a combination of peptides targeting your specific skin concerns. Incorporate these products into your daily skincare routine, applying them consistently to reap the full benefits of peptides.

Conclusion

In the ever-evolving landscape of skincare, Anti-Aging Peptides emerge as a promising ally in the battle against aging. Their ability to stimulate collagen production, target specific skin concerns, and protect against environmental damage makes them a valuable addition to any skincare regimen. By harnessing the power of peptides, you can unveil the secret to youthful, radiant skin and embark on a journey towards timeless beauty.
