    13.15   Renal cortex Version française
Cortex of a rodent kidney stained with PAS.

This field shows sections of several proximal convoluted tubules (A) and of a few distal convoluted tubules (B).

The brush border of the proximal convoluted tubules is PAS-positive, owing to the presence of glycoproteins associated with the plasma membrane of the microvilli.

The thin basement membrane of these tubules is also PAS-positive (blue arrows).

It is noticeable that the apex of the epithelial cells of the distal convoluted tubules (B) is not stained with PAS.

Stain: PAS-Hematoxylin
Magnification: ×500
