[Sex hormone regulation of progesterone and estradiol receptors in the cytosol of human endometrium in normal and pathologic pregnancy].
Hormonal control of progesterone and estradiol receptors was studied in the cytozol of short-lived culture of human endometrium in normal and undeveloping pregnancy. Endometrium was cultivated in the presence of estradiol or progesterone for 16 hours. In cultivation of normal endometrium with estradiol the content of estradiol receptors increased 4-fold in comparison with unstimulated tissue, and of progesteron receptors--3-fold. In cultivation of normal endometrium with progesterone the content of estradiol receptors rose 4--5-fold, and of progesterone receptors--3-fold. In cultivation of pathological endometrium with estradiol or progesterone the number of estradiol receptors was only doubled, and of progesterone receptors--increased only 1 1/2 times, this pointing to a diminished sensitivity of pathological endometrium to the regulating action of sex hormones.
