Electron micrograph of the junctional complex of intestinal epithelial cells of the rat shows the apical-most zonula occludens (tight junction), the zonula adherens (medium junction) and the macula ad...

This is a view of apical domains of two adjacent hepatocytes showing the junctional complexes that attach cells to one another. The canaliculus is defined by the cell membranes of two adjacent liver c...

This is a view of apical domains of two adjacent hepatocytes in the guinea pig liver, showing the junctional complexes that attach cells to one another. The bile canaliculus (BC) is defined by the cel...

Figures 81 (upper) and 82 (lower) from Chapter 3 (Junctional Specializations) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Septate junctions (upper, rectum; lower, testis) in the cockroach Periplane...

These examples of ependymal epithelium from the rat brain represent epithelia that lack zonulae occludentes. Further, there appears to be no consistent order to the junctional specializations that are...

Epithelia of invertebrates contain zona continua and septate junctions not found in mammals. Left, zonula continua from gut epithelium of a flea; right, septate junction from the midgut epithelium of...

Freeze fracture replicas of zonula occludens junctions from the large intestine of a tadpole (upper) and intestine of a post-metamorphic toad (lower). The occluding junction appears as a meshwork of...

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...
