podocyte A type of epithelial cell found in Bowman's capsule. Podocytes possess major footlike processes, each supporting a series of minor processes. These minor processes are interwoven with those from other podocytes to form a number of slits, through which filtration can occur. These slits (approximately 0.1 μm wide) permit the passage of all plasma constituents but act as a barrier to blood cells.
