[The nuclei of follicular cells do not control oocyte maturation in amphibians induced by gonadotropic hormones in vitro].
The inhibitory effect of actinomycin D (5 micrograms/ml) on maturation of the follicle-enclosed oocytes of Rana temporaria and Xenopus laevis induced in vitro by pituitary suspension and human chorionic gonadotropin, respectively, is not observed at low concentrations of the hormones. These data suggest that nuclei of the follicle cells are not involved in the control of the pituitary-dependent oocyte maturation in amphibians.
