HISTOCHEMICAL DEMONSTRATION OF MYOEPITHELIAL CELL ACTIVITY

Abstract

The specific localization of alkaline phosphatase in the myoepithelial cells of the mouse submaxillary gland was employed to demonstrate the activity of these cells following stimulation. The submaxillary glands of adrenaline‐treated mice contained myoepithelial cells whose diameter was significantly smaller than comparable sections from control or pilocarpine‐treated animals. This observation is discussed and related to the presumed contractility of the myoepithelial cells.
