The hypothetical gastraea concept, proposed by Haeckel (1874) to be an ancestral form common to all Metazoans, relied on the characterization of a gastrula stage in their embryonic development. The first steps that led to this characterization in Amp

Unlike biologists from several European countries, most French embryologists did not work from the onset on problems associated with the Spemann-Mangold organizer, though they were fully aware of the importance of the discovery. They preferred to sta

Experimental studies on amphibian embryos started mainly in Germany during the last two decades of the 19th century. At first, urodele amphibians were used much less frequently than anurans. At that time, embryological studies on urodeles were mostly

Pigmented axolotl coelomic oocytes were induced to form a gray crescent by simultaneous action of a gravity vector and of a heat-shock (36 +/- 0.5 degree C during 10-15 min), according to a previously described method. Those oocytes were subsequently

The karyotype ofSalamandra salamandra (Urodela, Salamandridae) was analysed from squash preparations of adult testes. The 24 chromosomes, ranged in decreasing order, can be classified into three principal groups of 8 chromosomes each. Only the elemen

Nuclear non-histone (NNH) proteins, both chromatin-associated and otherwise, have been prepared in defined conditions, either from nuclei or from washed chromatin. When these NNH proteins are homospecific, they produce inhibitory effects on morpholog
