[Early changes in the electric properties of the oocyte plasma membrane of Xenopus laevis during the reinitiation of meiosis induced by progesterone, para chloromercuribenzoate (PCMB) or the ionophore A 23187].
Progesterone, pCMB and ionophore -Mg++ triggers early and quite similar changes in the electrical properties of Xenopus laevis plasma membrane which may play a key role in the process of meiosis reinitiation.
