A confocal micrograph of a human embryo, with some remaining sperm cells, about five days after fertilization. The nuclei of both the sperm and cells of the embryo are stained purple, the tails of the...

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...

Wide field mosaic of mouse hippocampus immunolabeled for the hemichannel pore protein pannexin 1 (shown here in green), the astrocytic intermediate filament GFAP (colorized blue) and the gap junction ...

Transmission electron micrograph of intercalated disks with a desmosome from the atria of mouse cardiac muscle cells. The intercalated disks are where the junction of two opposing membranes of adjace...

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...

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...

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