title: Histochemical changes in acid and alkaline phosphatase activities in the growing follicles and corpora lutea of the rat ovary.
abstract: Changes in acid and alkaline phosphatase activities are studied histochemically in different components of the growing follicles and corpora lutea of different generations. Theca cells of the growing follicles showed strong acid phosphatase activity as compared to that observed in the oocyte and granulosa cells. Alkaline phosphatase activity is localized only in the theca interna cells of growing follicles. However, after ovulation with the formation of corpora lutea, the granulosa lutein cells also showed this activity. Changes in the histochemical distribution of the acid and alkaline phosphatases in the follicles and corpora lutea are discussed in relation to folliculogenesis and corpus luteum and regression.
