Enzyme histochemistry of cultured ovarian cells. III. Histochemical characteristics of bovine granulosa and theca interna cells grown separately in cell culture. 1977

A Stadnicka

Granulosa and theca interna cells were isolated from bovine preovulatory ovarian follicles. They were cultured separately but in the same conditions of cell culture. Both cell types, grown as monolayers, were investigated histochemically with special regard to the activity of several hydroxysteroid dehydrogenases: delta53betaOH-SDH, 17betaOH-SDH, 20alphaOH-SDH and G6P-DH. Bovine granulosa and theca interna cells during in vitro culture showed high activity of delta53betaOH-SDH and G6P-DH, the enzymes essential to progesterone biosynthesis. Enzyme pattern of cultured cells indicated continuation in vitro of luteinization, which in the normal preovulatory follicle of the bovine ovary begins prior to ovulation. There was investigated as well the influence of single doses of gonadotrophic hormones and estradiol on growth, lipid contents and enzymic activity of cultured in vitro bovine granulosa and theca interna cells.

UI	MeSH Term	Description	Entries
D010053	Ovary	The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.
