Advance of Apoptotic Mechanism in Mammalian Oocyte

Apoptosis is programmed cell death process, which plays an important role in the process of development of germ cells. In the process of growth and development of mammalian oocytes, in addition to the mature ovulation fertilization of the oocytes, the others are apoptotic at different stages of follicular oocytes. This paper summarizes the research progress of development of the main apoptosis mechanism and apoptosis pathway of mammalian oocytes, and lays a foundation for further studying growth, development and ovulation mechanism of oocytes.
