Glomerulus.  Mouse (385313)

The glomerulus is formed by closely packed capillary loops. The capillary endothelial cells are fenestrated. This mouse was perfused to clear blood from its vascular system before fixation, therefore these capillaries are essentially empty.  Cell bodies of 3 podocytes covering the outer surface of the capillaries are shown in a row in the upper field. A mesangial cell sitting between the capillaries is in the lower middle field.
