【摘要】 综述近年来哺乳动物胚胎着床前这一发育阶段基因表达与调控的研究进展。早期胚胎发育受母源型 ,即卵母细胞内 m RNA和蛋白质的调控 ,随着母型 m RNA的消耗 ,合子型基因取而代之进行合子型调控 ;其中合子型基因激活是调控过渡的关键事件。更多还原

【Abstract】 This review summaries current development on the gene expression and control of mammalian preimplantation embryo.The early development of embryo is controlled by maternal m RNA and proteins;Zygotic regulation replaces itwith maternal m RNA reducing;Zygotic gene activation is very essential during the transition from maternal to zygotic regulation.更多还原
