Project

Mammalian oocytes with low meiotic competence and their progress through the meiotic maturation (GP524/09/P435)

The progression of mammalian oocyte meiosis is accompanied by major changes and cytoplasmic maturation. During the growth phase, oocyte acquires the meiotic competence to finish meiotic maturation till to metaphase II stage. Ooc...
