  • Title: The effect of 17 beta-estradiol and progesterone on prostaglandin production by human endometrium maintained in organ culture.
    Author: Abel MH, Baird DT.
    Journal: Endocrinology; 1980 May; 106(5):1599-606. PubMed ID: 7363865.
    Abstract:
    Endometrium collected from 18 normal women at various stages of the menstrual cycle was maintained in organ culture for periods of 6 days. Both prostaglandin F2 alpha (PGF2 alpha) and PGE were detected in medium from late proliferative (days 10-14; n = 13) and late secretory (days 20-26; n = 5) endometria cultured in the absence of exogenous steroids. During the first 48 h in culture, the output of PGF2 alpha by secretory endometrium was significantly greater than that of proliferative tissue. The addition of 17 beta-estradiol to the culture medium at doses ranging from 1.0-100.0 ng/ml induced a significant increase in the output of PGF2 alpha by secretory but not proliferative endometria. The addition of progesterone at doses ranging from 5.0-500.0 ng/ml significantly reduced the output of PGF2 alpha and PGE by both proliferative and secretory endometria and prevented the 17 beta-estradiol-stimulated increase in PGF2 alpha output by secretory tissue.
