Glial cells in the nerve cord of the annelid worm, Aphrodita aculeata are rich in 10 nm filaments, and desmosomes are abundant. Figure 89 from Chapter 3 (Junctional Specializations) of 'The Cell, 2nd ...

Upper: a gap junction on the boundary between two hepatic cells shows a typical narrow and straight interface. Lower: in some preparations, gap junctions appear curved, and project into one of the ce...

Replica of a freeze-fractured gap junction presents the inner half-membrane on one of the cells (P-face, lower half of the micrograph) and the the outer half-membrane of the other cells (E-face, upper...

These examples of ependymal epithelium from the rat brain represent epithelia that lack zonulae occludentes. Further, there appears to be no consistent order to the junctional specializations that are...

Epithelia of invertebrates contain zona continua and septate junctions not found in mammals. Left, zonula continua from gut epithelium of a flea; right, septate junction from the midgut epithelium of...

Freeze-fracture preparation of a continuous junction on the lateral surface of epithelial cells from the gut of a flea. Meandering ridges appear to be on the P-face of the replica. Figure 80, by Susu...

Photoactivation localization microscopy image (PALM) of a human foreskin fibroblast expressing Dronpa-alpha-actinin (red) and tdEos-vinculin (green). This image reveals that although conventional dif...

This total internal reflection (TIRF) image of unconverted tdEos-paxillin (green) and PsCFP20-zyxin (red) demonstrates that these two proteins are almost completely colocalized when observed with diff...

Adhesion dynamics in a migrating CHO K1 cell. CHO K1 cells expressing paxillin-mEGFP were plated onto coverslips that were preincubated with a solution of 5 ug/ml fibronectin overnight at 4o C. The ...

Gap junctions isolated from mouse liver and negatively stained with uranyl formate. At higher magnification, the 8-9 nm particles, or connexons, have a central 1.5-2 nm electron dense pore. Images b...
