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...

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...

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...

A single frame from a time-lapse animation of FlAsH-labeled MDCK cells expressing Cx43-4C309/337 (green) showing their rearrangement and fate during and after mitosis. In the time-lapse series, which...

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; ...

Single computed slice through a double tilt electron tomogram of a lamellar structure observed in HeLa cells transfected with mutant connexin 50, imaged using intermediate voltage electron microscopy,...

Maximum intensity projection of a confocal z series of MDCK cells expressing Cx43-GFP-4C imaged with confocal microscopy. This image has been downsampled from the raw data image, and time lapse series...
