[Hormonal regulation of estrogen and progesterone receptor biosynthesis in human endometrial tissue culture]

Estradiol and progesterone effects on the biosynthesis of estrogen and progesterone cytoplasmic receptors have been studied in the endometrium culture tissue of pregnant women. It was established that in a 48-hour culture estradiol stimulated the biosynthesis of its own and progesterone receptors. Under the same conditions progesterone stimulated the biosynthesis of estrogen receptors but did not affect the biosynthesis of its own receptors.
