Observations cytologiques et cytochimiques sur la maturation de l'oocyte chez les urodèles

In vitro addition of progesterone to oocytes taken out of Pleurodeles females which had received injections of Pregnyl markedly increases the frequency of maturations. Progesterone alone induced the maturation, in a high percentage of the cases, in Ambystoma mexicanum oocytes taken out of 3 females which had been reared under special conditions. Cytological analysis has not shown any major difference in the maturation of Urodeles and Anurans. The significance of these results is discussed.SCOPUS: NotDefined.j
