Aprocrine sweat glands in a dog.

The aprocrine sweat glands have a secretory portion and a ductal portion. The epithelium of the secretory portion contains cuboidal or low columnar cells, The cytoplasm is eosinophilic and may have apical “blebs” that project into the wide lumens. Contractile myoepithelial cells are found between the secretory cells and the basal lamina. However, these may be difficult to make out without special stains. The duct portion contains two layers of low cuboidal cells. The aprocrine type of sweat gland is well developed in domestic mammals and are located throughout most of the skin. Original mag. 50x H&E.
