Localization of acid phosphatase in lysosomes of pituitary folliculo-stellate cells following estrogen withdrawal from primed male rats.
Acid phosphatase was localized in lysosomes of non-granulated, folliculo-stellate pituitary cells 72 h after estrogen was withdrawn from primed male rats. The appearance of lysosomes and the accumulation of lipid droplets in folliculo-stellate cells coincide with the clearance of lipid from pituitary mammotropes. Positive identification of lysosomes supports our proposal in a previous study that folliculo-stellate cells are phagocytic.
