Oocyte Maturation

How does an oocyte become an egg?

Learning Objectives

  • Review hormonal interactions in mammals and frogs.
  • What is unusual about the mechanism of action of progesterone in promoting oocyte maturation?
  • How did Yoshio Masui demonstrate the presence of maturation promotion factor and cytostatic factor?
  • What is MPF, and how was its identity determined?
  • What is CSF, and how was its identity determined?
  • Review the interactions among p34, cyclin and c-MOS
  • What effect does alpha- amanitin have on progesterone-induced amphibian oocyte maturation? Why?
