From: Kit ligand promotes first polar body extrusion of mouse preovulatory oocytes
Lack of effect of KITL in the conditioning of oocytes for development into preimplantation embryos. COCs obtained from preovulatory follicles were cultured without (control) or with KITL (5 ng/ml) for 17 h. After progression into the MII stage, oocytes were inseminated and cultured for 5 more days without hormones. The percentage of MII oocytes developing into 2-cell-stage embryos and the percentage of 2-cell-stage embryos developing into blastocyst-stage embryos were evaluated (n = 4, 174–295 oocytes per experimental group). *, P < 0.05 vs. control group.
