Hilus cells from human postmenopausal ovaries: gonadotrophin sensitivity, steroid and cyclic AMP production.

Abstract:

:Strips of ovarian hilar tissue taken from 11 post-menopausal women were examined histologically and found to contain clusters of hilus cells in contiguity with non-myelinated nerve fibers. No other steroidogenically active structures were found. Specimens from these strips were incubated for 30 and 240 minutes in Krebs bicarbonate buffer containing 5.5 mM glucose and 1% bovine serum albumin. The specimens produced measureable amounts of androstenedione, estradiol-17 beta and progesterone in vitro. The major steroid formed was androstenedione, and this pattern of steroidogenesis appeared similar to that of postmenopausal ovarian stroma. However, the amounts of steroids formed were considerably higher than in stromal tissue. This implies that the hilus cells possibly may be of greater importance, qualitatively, than the stroma cells for steroidogenesis in the postmenopausal ovary. Addition of hCG to the incubated specimens elicited increase in both cyclic AMP formation and steroid synthesis, especially of estradiol-17 beta, indicating a preserved responsiveness to gonadotrophin in hilus cells from postmenopasual ovaries.
