Description
Kidney cortex stained with periodic acid Schiff PAS method. The PAS method allows the proximal convoluted tubules most of the ones seen in the picture to be easily distinguished with a PAS + brush border, and the distal convoluted tubules, with broader lumen, lower epithelium and devoid of brush border. In the image, the distal tubules are sparse, but some can be seen across the image
