Podocytes (or visceral epithelial cells) are cells in the Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. The Bowman's capsule filters blood, retaining large molecules such as proteins while smaller molecules such as water, salts, and sugar are filtered as the first step in forming urine.The long processes as foot projections called pedicels, of the podocytes wrap around the capillaries, and leave slits between them.
