title: Granulosa-lutein cell growth differentiation factor-9 (GDF-9) messenger RNA and protein expression in in vitro fertilization (IVF) cycles: relation to characteristics of ovulation induction and IVF.
abstract: Granulosa-lutein cell growth differentiation factor-9 (GDF-9), a member of the transforming growth factor beta (TGF-beta) superfamily, is an oocyte-derived factor expressed throughout the development of the maturing follicle and is essential in early follicular development and fertility. Both GDF-9 messenger RNA and protein are detected in granulosa-lutein cells. A statistically significant correlation between GDF-9 expression and the number of dominant follicles on the day human chorionic gonadotropin is administered also is demonstrated. Human granulosa-lutein cell GDF-9 expression may play a role in folliculogenesis dependent on follicle-stimulating hormone in the in vitro fertilization cycle.
