Description
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, and extend from 0.1 - 0.5µm beyond the microvilli, make up the glycocalyx that encompasses the brush border of the intestine. Filaments from each microvilli radiate and intermingle with those from adjacent microvilli to form a near-continuous network. Micrographs courtesy of Susumu Ito; upper panel was reprinted with permission from Fawcett, D. J. (1965) Histochem. Cytochem. 13: 75-95, and are figures 17 (upper) and 18 (lower) from Chapter 1 (The Cell Surface) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. A PDF copy of the accompanying chapter is available on the ASCB's BioEDUCATE website.
