ResumoThis study investigates steady-state level of bone morphogenetic protein-15 (BMP-15) mRNA in caprine follicles, and the effects of BMP-15 on in vitro development of preantral follicles. Ovarian fragments were cultured for one or seven days in Minimal Essential Medium (MEM+) with BMP-15 (0, 1, 10, 50, 100 or 200 ng/mL), and further analyzed by histology, transmission electron and fluorescent microscopy. BMP-15 mRNA in secondary follicles was higher than in primordial and primary follicles. After seven days, 10, 50 or 100 ng/mL of BMP-15 maintained the percentage of normal follicles similar to the control (non-cultured), and increased the oocyte and follicle diameters when compared to the control and MEM+. BMP-15 at 100 ng/mL increased the secondary follicles and maintained their ultrastructural integrity. In conclusion, the BMP-15 mRNAs were detected in all follicular categories. BMP-15 (100 ng/mL) maintained the integrity and promoted the growth of caprine preantral follicles cultured for seven days.
