title: [Progress in research on oocytes parthenogenetic activation].
abstract: Parthenogenetic activation is a procedure that an oocyte at meiosis II stage is activated into mitosis by some chemical or physical stimulation other than a sperm and the embryo is formed in the absence of any contribution from a male gamete. The activation of oocyte is the result of calcium ion oscillations and deactivation of some cytokines such as maturation promoting factor, mitogen-activated protein kinase and cytostatic factor. Parthenogenetic activation is artificially induced by various kinds of physical and/or chemical methods. The main activation method of human oocyte is chemical methods. The rates of activation and cleavage depend on the age, origin,and culture conditions of the oocyte.
