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...

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...

Gap junctions from a granulosa cell of a rat ovarian follicle. Variability in size of the gap junctions is likely an artifact of the freeze fracture preparation. Figure 99 from Chapter 3 (Junctional ...

Gap junctions in ciliary epithelium under conditions of oxygenation (upper) and anoxia (lower), in tissue prepared by ultrarapid freezing using liquid helium. Under oxygenated conditions, the connexo...

Papillary muscle from cat heart shows a step-like end-to-end junction of two cardiac muscle cells. The longitudinally oriented lateral cell boundaries are straight and exhibit extensive gap junctions...

Gap junctions in papillary muscle from cat heart. These communicating junctions are responsible for the spreading wave of depolarization through the myocardium. Desmosomes can also be found on the l...

Upper panel, adjoining portions of two cells in the stratum spinosum of hamster cheek pouch epithelium shows desmosome junctions between two cells. Lower, a portion of the basal surface of a cell in ...

Transmission electron micrograph of the junctional complexes at the intersection of three hepatocytes. This image was taken from liver tissues from an ethanol fed rat and also shows the bile canalic...

Upper panel shows a typical zonula occludens of rat intestinal epithelium, prepared using freeze fracture techniques. A network of intersecting strands on the P-face, and a complementary pattern of g...

Representative examples of gap junctions from vertebrates (ciliary epithelium from the eye of a Macaca mulatta, upper) and invertebrates (inverted gap junctions from cells of the mid-gut of the horses...
