Scanning electron micrograph reveals microvilli on the surface of HeLa cells in culture. Image by Keith Porter. Figure 31 from Chapter 2 (Specializations of the Free Surface) of 'The Cell, 2nd Ed.' b...

Surface of a mouse oocyte This transmission electron micrograph shows the cortex of a mouse oocyte that was undergoing fertilization. The sample was fixed using glutaraldehyde and osmium tetroxide, em...

Transmission electron micrograph of rat intestinal colon showing apical microvilli. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of Medicine.

Electron micrograph of epithelial cells of the parotid gland of the gerbil, prepared by rapid freezing and freeze substitution. Microvilli and microplicae, which expand the extracellular surface alon...

Cells from peritoneal cavity exudate of the mouse, exposed to sodium azide at 22°C for 22 minutes. The macrophage in the field of view has extended long microvilli, showing a rapid response to change...

Rapid extension of microvilli on the surface of a peritoneal macrophage, induced by treatment with a metabolic inhibitor, sodium azide, after 20 minutes at 22° C. Microvilli on neighboring lymphocyt...

This electron micrograph shows a region of the brush border of the cat intestine. Tufted and branched polysaccharide filaments, each a few nanometers thick, extend from the microvilli to make up the ...

This electron micrograph highlights a darkly-stained glycocalyx rim of the brush border of the intestinal epithelium of the cat, stained en bloc with colloidal thorium. The glycocalyx is composed of ...

Scanning electron micrograph of the lumenal surface of the toad bladder shows the boundaries of four polygonal squamous epithelial cells surrounding a mitochondrial-rich cell bearing short globular mi...

The final stages of cell division is captured in the scanning electron micrograph. Two daughter cells are still interconnected by slender strands of membrane (white arrow at center of image). Lamell...
