Growth differentiation factor 9 (GDF9) is an oocyte derived growth factor in the transforming growth factor β (TGF-β) superfamily. It is highly expressed in the oocyte and has a pivotal influence on the surrounding somatic cells, particularly granulosa, cumulus and theca cells. Paracrine interactions … See more Growth/differentiation factor 9 is a protein that in humans is encoded by the GDF9 gene. Growth factors synthesized by ovarian somatic cells directly affect oocyte growth and function. … See more GDF9 acts through two receptors on the cells surrounding the oocyte, it binds to bone morphogenic protein receptor 2 (BMPRII) and downstream to this utilizes the TGF-β receptor … See more Role in Oogenesis A lack of GDF9 causes pathophysiological alterations in the oocyte itself in addition to severe follicular abnormality.
