13.11 Renal corpuscle

Version française

Thin section of a renal corpuscle with an arteriole connected to the capillaries (C) of a glomerular tuft.

The large cells forming the wall of this arteriole (double-headed arrows) are modified smooth muscle cells called juxtaglomerular cells. They are endocrine cells that secrete renin. Along with the macula densa and mesangial cells, they form the juxtaglomerular apparatus.

The other cells of the glomerulus and of the Bowman’s capsule are also labelled: endothelial nuclei (E) of capillaries, podocytes (green arrows) and cells of the parietal layer (arrowheads). The Bowman’s space (*) and the renal tubules (T) surrounding the renal corpuscle are also identified.
