Transmission electron micrograph of a section close to the luminal surface of the rat intestinal epithelium showing a tight junction (zonula occludens) extending diagonally across the image from upper...

Transmission EM showing adherens junctions between cells of the enveloping layer of a 24 hr (prim-5) Zebrafish embryo. Specimens fixed in Karnofsky's (overnight at 4˚C) followed by postfixing in 4% ...

Transmission electron micrograph of tight junction (zonula occludens) between adjacent plasma membranes in the distal kidney tubule. The darkly staining horizontal structure forms the junctional compl...

Freeze fracture replica of zonula occludens junctions from the small intestine of a Xenopus laevis tadpole. The occluding junction appears as a meshwork of ridges on the P-face or a corresponding pa...

Sertoli-Sertoli occluding junctions from guinea pig testis. Figures 67 (left) and 68 (right) from Chapter 3 (Junctional Specializations) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. A PDF copy of t...

Transmission electron micrograph of a tight junction (zonula occludens)between two cells in a section of tissue from a rat thyroid. Image made available by James D. Jamieson and the Department of Cel...

Transmission electron micrograph of two frog epithelial cell cells showing the tight junction complex running horizontally in this image. Additional reference: Farquhar, M.G. and G.E. Palade. 1965. ...

Transmission EM showing tight junctions apically and adherens junctions laterally between cells of the enveloping layer of a 24 hr (prim-5) Zebrafish embryo. Specimens fixed in Karnofsky's (overnight...

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...

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) ( (...
