These two micrographs show the outer cell surface of the epithelial cell border in intestine (upper) and stomach (lower) tissue. This surface, called the glycocalyx, is composed of negatively charged...

Confocal micrograph showing Shigella bacteria (pink) invading the intestinal lining. The bacteria infects the cells by high-jacking the cell's internal actin skeleton (green) to facilitate its entry i...

Transmission electron micrograph of glutaraldehyde fixed pancreatic acinar cell showing the characteristic features of nuclear chromatin with this preparative method. Darkly staining heterochromatin (...

Nomaski image of live guinea pig pancreatic acinar cells. Image corresponds to Figure 1 in Proc Natl Acad Sci U S A. 1972 Oct;69(10):3028-32. Image made available by James D. Jamieson and the Departm...

Scanning electron micrograph of single guinea pig pancreatic acinar cell. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of Medicine.

Filaments extend from microvilli of the epithelial cells in the intestine of the bat, Moytis lucifugus in these two high magnification electron micrographs. These filaments, which are 2.5-5nm thick, ...

Figure 390 from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Secretory granules of an alpha cell (upper part of the micrograph) and two beta cells (lower) from an ...

Early transmission electron micrograph of thin section of acinar cell on guinea pig pancreas. Rough endoplasmic reticulum, Golgi vesicles and portion of a zymogen granule are seen. Image made availab...

Upper panel shows a typical zonula occludens of rat intestinal epithelium, prepared using freeze fracture techniques. A network of intersecting strands on the P-face, and a complementary pattern of g...

Intestinal epithelium from the adult midgut of Drosophila melanogaster were immuno-stained for the cell periphery (integrin, red), nuclei (DAPI, blue) and stem cells (green). Nuclei are not seen in th...
