[Granulosa cells as indicators of oocyte quality].
Granulosa-cumulus cells are located around the oocyte and may be involved in competence acquisition and in the resumption of oocyte meiosis. We assessed Bax expression in granulosa-cumulus cells and its correlation to in vitro resumption of oocyte meiosis in women presenting PCOS (polycystic ovarian syndrome), as well as the role of the chemokine SDF1-CXCL12 in human preovulatory follicle in the follow-up of granulosa cell survival and embryo quality in IVF.
