of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Scanning electron micrograph of the epidermal surface of the flatfish sole Parophrys detulus shows a labyrinth of surface ridges. Image from Fahrenbach,...

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...

Hela cells transiently transfected with EGFP-GL-GPI show the organization of the membrane thru the distribution of GPI anchored protein. This image is the maximum z projection image that accompanies...

Scanning electron micrograph of a 3T3 cell growing in culture. Complexity and diversity of structure across the cell surface is apparent in the this image that s courtesy of Susan Brown. Figure 48 fr...

A colorized scanning electron micrograph of a human egg, which is the huge cell colored yellow at the bottom of this image. The follicle cells that surround it (top) send out long projections that pen...

Hela cells transiently transfected with EGFP-GL-GPI show the organization of the membrane thru the distribution of GPI anchored protein. This image is the z stack that accompanies the related maximu...

Scanning electron micrograph of the epidermal surface of lamprey larvae. A row of microvilli outline the polygonal borders between cells, while short microvilli cover the external surface in a reticu...

Cultured retinal pigment epithelial cells immunofluorescently labeled for adaptor protein-2 (AP2) (green) and nucleus (blue). The cells were fixed in 2% PFA and 0.5% Triton X-100 for 2 minutes follow...

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...
