Reorganization of the Endoplasmic Reticulum and Development of Ca2+ Release Mechanisms During Meiotic Maturation of Human Oocytes1
8 Jul 2010
Abstract excerpt
Oocyte maturation in rodents is characterized by a dramatic reorganization of the endoplasmic reticulum (ER) and an increase in the ability of an oocyte to release Ca(2+) in response to fertilization or inositol 1,4,5-trisphosphate (IP(3)). We examined if human oocytes undergo similar changes during cytoplasmic meiotic maturation both in vivo and in vitro. Immature, germinal vesicle (GV)-stage oocytes had a fine...
