Progesterone and androgen secretion by isolated cultured bovine corpus luteum cells: effect of LH, hCG, PRL, estradiol 17beta and testosterone



Progesterone and androgen secretion by isolated cultured bovine corpus luteum cells: effect of LH, hCG, PRL, estradiol 17beta and testosterone



Folia Histochemica et Cytobiologica 23(1-2): 11-16



Primary cell cultures of bovine corpora lutea were used in order to examine their morphology and secretion of progesterone and androgen in vitro. The cells were grown as monolayers up to 6 days at 37 degrees C medium 199 supplemented with 10% calf serum. The concentration of progesterone and androgen was measured using appropriate radioimmunoassays [1,3] respectively. Luteal cells were cultured with addition of the following amounts of hormones: 100 ng LH, 10 i.u. hCG, 100 ng PRL, 150 ng Estradiol 17 beta and 150 ng Testosterone/ml of culture medium. The luteal cells also created considerable amounts of androgens. It was found that only estradiol added to the culture medium caused an increase in the level of testosterone. Progesterone secretion following the addition of hormones increased under the influence of LH, T, and E2 in statistically significant manner while hCG and PRL had no statistically significant effects.
