abstract：:In mature mammalian oocytes, cortical f-actin distribution is polarized, as evidenced by a prominent cap subtended by the metaphase II (MII) spindle. Formation of a polarized actin cap is a consequence of a complex actomyosin-driven contractile process that directs polar body extrusion. Human mature oocytes also displ...
