| Résumé : | The localization of alkaline phosphatase has been studied in the early development of Amphibian embryos; there is very little enzyme present, even in the nuclei and the chromosomes, during cleavage and gastrulation stages. A marked increase of the enzyme content of both nuclei and yolk occurs only in post-neurula stages. Alkaline phosphatase probably plays no important part in thymonucleic acid synthesis, morphogenetic movements and primary induction, but might be essential in organogenesis. © 1946 Birkhäuser Verlag. |
