Lettre à l'éditeur

Résumé :

DURING the maturation of amphibian eggs, Feulgen positive bodies appear in the cytoplasm1,2: they become visible when the nuclear membrane breaks down and are undoubtedly of nuclear origin. Their appearance is not prevented by treatment of the eggs with actinomycin, puromycin or cycloheximide3, which block the maturation of amphibian eggs3,4. According to Dettlaff4, actinomycin suppresses maturation only during the initial hormone-dependent phase in Rana. In Xenopus we found3 that all stages of maturation were sensitive to actinomycin. © 1967 Nature Publishing Group.
