Nuclear and cytoplasmic determinants involved in the regulation of mammalian oocyte maturation.

abstract：:The transcription factor OCT-4 is regarded as a critical factor in controlling mammalian early embryonic development because of its role in toti-/pluripotency. In human preimplantation embryos, OCT-4 studies are limited to RNA analysis of abnormally developing embryos. This study thoroughly investigated the expression...
