Fig. 5From: Concentrations of oocyte secreted GDF9 and BMP15 decrease with MII transition during human IVMRelative expression of seven genes from the GDF9 and BMP15 signaling pathways in cumulus cells from human oocytes before IVM (GV(Fresh), n = 24), and after IVM (GV, n = 21; and MII, n = 27). GV and MII respectively refer to germinal vesicle and metaphase II stages. (A) BMPR2, (B) ALK5, (C) ALK 6, (D) SMAD2, (E) SMAD3, (F) SMAD1, and (G) SMAD5.
