defined maturation medium with 100 μM CYS or 100 μM β-ME showed no stimulatory effect on oocyte maturation, embryo cleavage, or blastocyst formation after PA. β-ME treatment during IVM decreased embryo cleavage after SCNT compared to pFF or PVA treatments, but no significant difference was found in blastocyst formation (7-16%) among the four treatment groups. The results indicated that maturation of oocytes for 42 h was beneficial for the development of SCNT embryos. Furthermore, the defined...
