Despite the recognition of the physiological importance of the BMP system in regulation of gonadotropin action in the ovary, molecular mechanisms of BMP-15 effect on oocyte and somatic follicular cell functions remain poorly understood. The objective of this study was to determine the effect of BMP-15 on the FSH/LH-stimulated synthesis of hyaluronan (HA) by oocyte annulus complexes (OCC) and progesterone by OCC and granulosa cells (GC) in the presence or absence of serum using primary porcine cultures. In addition, the effect of BMP-15 on oocyte maturation- and steroidogenesis-related transcripts after 4, 8, 16, and 24 hours of cultivation was evaluated using real-time RT-PCR. We demonstrated that the FSH/LH-induced cumulus expansion was accompanied by a significant increase in CD44, PTGS2, CYP11A1 (at 4 h) and AREG, HAS2, TIVFAIP6, STAR (at 8 h) mRNAs. While FSH/LH-stimulated total HA synthesis by OCC was not affected by BMP-15 in serum-supplemented medium, its retention within the complex was significantly increased after the action of BMP-15 in comparison to FSH/LH alone (P < 0.001, 65% versus 35%. respectively). Moreover, we detected a significant increase in the expression of AREG and TNFAIP6 (both at 16 h), and CYPIIA1 (at 24 h) in FSH/LH-stimulated OCC due to the action of BMP-15 compared to complexes cultured only with FSH/LH. In the presence of serum, BMP-15 markedly increased FSH/LH-stimulated progesterone secretion by OCC (about 69%) and induced a significant decrease in FSH/LH-induced progesterone release by GC (about 35%) compared to FSH/LH alone. The present results indicate that the addition of BMP-15 to the gonadotropin-stimulated OCC cultured in serum-supplemented medium might improve oocyte-cumulus maturation.
