BMP-15 and GDF-9 are synthesized as 249-295 amino acid N-terminal prodomains and 125-139 amino acid mature domains. The mature domains of GDF-9 and BMP-15 form 40 kDa and 34 kDa homodimers respectively and 37 kDa heterodimer 1,2. Growth Differentiation Factor 9 (GDF9) and Bone Morphogenic Protein 9 (BMP15) are oocyte secreted factors and play key roles in promoting follicle growth, maturation and oocyte competence 1,3-5. However, the action of BMP15 and GDF9 varied with respect to the species of origin and the stages of follicle development. Oocyte competence is an intrinsic developmental potential that allows a mature oocyte to become fertilized and develop to an embryo. Oocyte competence is achieved by long course of molecular, biochemical and morphological changes4. Recent study suggests AMH production is regulated by oocyte-secreted factors in primary human cumulus cells and the combination of GDF9 + BMP15 potently stimulates AMH expression6. Altered level and activity of GDF9 is implicated in premature ovarian failure and polycystic ovarian syndrome, implicating GDF9 in the etiology of these conditions 7-9.
