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...

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...

Mouse tracheal epithelia cells (MTEC) were grown at air-liquid interface to induce differentiation, centriole amplification and ciliogenesis. Cells were fixed using ice-cold methanol for 10 min. Sampl...

Junctional complex between two cells in the epithelium of the rat intestinal mucosa. The tight junction (also known as zonula occludens) is the structure located nearest to the lumen. The elimination ...

Junctional complex between two cells in the epithelium of the rat intestinal mucosa. The tight junction (also known as zonula occludens, ZO) located nearest to the lumen extends from arrow 1 to arrow ...

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...

Typical organization of gap junctions as seen in thin sections (upper) and replicas of freeze-fractured cell membranes (middle and lower). Upper, gap junction from the saccular macula of a goldfish; ...

Mouse tracheal epithelia cells (MTEC) were grown at air-liquid interface to induce differentiation, centriole amplification and ciliogenesis. Cells were fixed with ice-cold methanol for 10 min. Sample...
