CIL:11397 - http://cellimagelibrary.org/images/11397

Description: Figure 218 from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. The typical structural organization of mitochondria is revealed in this longitudinal section of a mitochondrion and surrounding cytoplasm from pancreas of the bat, Myotis lucifugus. It is bounded by a smooth outer membrane about 7nm thick. An inner membrane has infoldings called cristae that project into the interior of the organelle.

CIL:50519 - http://cellimagelibrary.org/images/50519

Description: We examined the structural organization of cytoskeletal components and membrane systems in neurons of well preserved biopsy material from Alzheimer’s disease (AD). Information was obtained from thin sectioned material using conventional electron microscopy and from thick sections with the high voltage electron microscope. Stereo viewing and computer assisted serial reconstruction techniques were employed to visualize three-dimensional relationships among cytoplasmic components of cortical neurons.

CIL:45553 - http://cellimagelibrary.org/images/45553

Description: Imaging an HIV infected dendritic cell reveals numerous viral particles at the tips of filopodia. Actin-based membrane extensions from the dendritic cell are phallodin stained (red). HIV particles (white) decorate the filopodial terminal ends. To label viral particles, a construct containing eGFP at the C-terminus of HIV matrix was expressed. The nucleus of the cell is stained with DAPI and is represented in cyan.

CIL:34603 - http://cellimagelibrary.org/images/34603

Description: A cross section of cilium through the cilium-basal body complex extending from the cilium to the transition zone between the cilium and basal body and ending at the proximal tip of the basal body. In cross section the 9 + 2 axoneme of the cilium stands out. The plasma membrane covers the axoneme and is continuous with the plasma membrane covering the cell body. Each doublet tilts inward to the tangent of the axonemal cylinder. Two arms, an inner arm and outer arm, extend from the complete microtubule of each doublet. These arms have ATPase activity and are called dyneins. They cause one doublet to slide against the adjacent doublet. Other protein links, like the spokes, in the axoneme are elastic and induce the characteristic bending of the cilium and prevent excess sliding as the doublets slide past each other.

CIL:41017 - http://www.cellimagelibrary.org/images/41017

Description: Laser scanning confocal micrograph of a water flea, Daphnia atkinsoni. This specimen has a "crown of thorns," a defensive trait induced in offspring only when the parents sense chemical cues released by one of their main predators, the tadpole shrimp Triops cancriformis. The water flea's exoskeleton (exterior structure, green) and subcellular details within the organism (nuclei - tiny blue dots) are both visible.

Spooky Eyes - Happy Halloween - Image of the Week - October 28, 2019

CIL:39022 - http://cellimagelibrary.org/images/39022

Description: Confocal micrograph showing the connections of the visual system in a four-day-old zebrafish embryo. Staining of the neurons, glia and optic nerve illustrate the connections between the retina and the brain. The retina is a multi-layered structure of retinal neurons that processes light information in the eye. The ganglion cell layer is closest to the bulb of the eye moving out towards the layer that contains the light sensitive cells - the rods and cones - towards the back of the retina. Both the retinal ganglion cell layers and photoreceptor cell layers are shown in cyan. The glial cells are shown in purple. The optic nerve (cyan) transmits information from the eye to the brain. The point at which the optic nerves meet is known as the optic chiasm.
