This pair of confocal micrographs demonstrates how a disease-causing strain of E. coli bacteria brings about diarrhoea by breaking down the waterproof barriers between the cells. The bacteria are seen...

High magnification serial block face scanning electron microscopy image series of a cell-cell contact region between three cells in the interior of the multilayered region of an FGF2 (fibrolast growth...

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 ...

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,...

Occluding junctions in Sertoli cells of ram and rat testis. Multiple focal sites of membrane fusion are indicated by arrows in each panel. Underlying these sites, associated bundles of filaments and...

A time-lapse movie showing the dorsal pouch formation and migration of heart-anchoring cells (HANCs) in the Drosophila embryo expressing ubi-DE-cad-GFP (Shg-GFP). Shg-positive HANCs corresponding to t...

ZO-1 polypeptides lacking the unique-6 (U6) motif are concentrated within disorganized strands on the lateral surface of MDCK cells. MDCK II cells transfected with deltaU6 (A–F) or ZNG (aa1-806) ( (...

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...

High magnification serial block face scanning electron microscopy image series of a cell-cell contact region between four cells in the interior of the multilayered region of an FGF2 (fibroblast growth...
