Freeze fracture replica of zonula occludens junctions from the small intestine of a Xenopus laevis tadpole. The occluding junction appears as a meshwork of ridges on the P-face or a corresponding pa...

Sertoli-Sertoli occluding junctions from guinea pig testis. Figures 67 (left) and 68 (right) from Chapter 3 (Junctional Specializations) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. A PDF copy of t...

Figure 396 from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Axodendritic synapse from mammalian (rat) central nervous system. Arrow points to one region of the ...

This photoactivation localization microscopy (PALM) image of tdEos-vinculin (red) and Dronpa-paxillin (green) illustrates that vinculin and paxillin are segregated into interlocking microdomains withi...

Microtubules in a Rac1(Q61L)-expressing PtK1 cell injected with Pak inhibitory fragment PBD/ID(H83L). Microtubules do not exhibit retrograde flow and undergo very little net growth. Epifluorescence i...

Stratified squamous epithelium from the esophagus of the rat. Keratin filaments (tonofilaments, arrows) are sparse, and desmosomes are few (see inset), in the basal cell layer of this tissue. Figures...

Confocal micrograph showing nerve cells growing along fibers (purple) made from a specially modified silk that is similar to that made by spiders and silkworms. Schwann cells, whose nuclei are shown i...

Colorized transmission electron micrograph of a platinum replica showing the cytoskeletal organization of stubby dendritic spines in extracted hippocampal neurons after 14 DIV. This imge shows branche...

Montage image of a brain stem from a Brainbow transgenic mouse. In Brainbow mice, neurons randomly choose combinations of red, yellow and cyan fluorescent proteins, so that they each glow a particular...

Confocal image of pastel neurons in the hippocampus of a "Brainbow" mouse brain, with each neuron expressing a distinct color. In Brainbow mice, neurons randomly choose combinations of red, yellow a...
