title: [The effect of a nerve growth factor from different biological sources on the spontaneous maturation of mouse oocytes and on the parthenogenetic activation of pronucleus formation].
abstract: The paracrine role of the nerve growth factor (NGF) in oocyte maturation is analysed. It is shown that the addition of mouse beta-NGF to the serum-free culture medium in doses of 100, 10 and 1 ng/ml induces reinitiation of meiosis in mouse oocytes after gonadotrophic stimulation. It is identified that oocytes without cumulus cells demonstrate a 2-3 fold increase in the rate of parthenogenetic pronucleus formation in comparison with the control. Similar results are obtained using bovine beta-NGF. It is supposed that the oocyte surface has a receptors to beta-NGF.
