Cortex of feline kidney.
Description:This slide was stained with PAS-hemotoxylin. Note the bright staining of the basal lamina surrounding the tubules as well as in the glomeruli. The brush border of the proximal convoluted tubules also stained a touch of pink. The epthelial cells of the proximal convoluted tubules are cuiboidal with centrally located nuclei. The lateral cell waslls cannot be seen. The distal tubules have more open lumens. The cells are smaller and the nuclei are closer to the lumen than those in the proximal tubules. Note the absence of a pink brush border in the distal tubules. Original mag. 133x. PAS_Hematoxylin. Cortex. Kidney. Urinary System. Cat.
