Amphioxus, a cephalochordate, is the closest living relative to the vertebrates. In order to investigate the molecular mechanisms of the early embryogenesis of amphioxus, we constructed a neurula embr...
Levels of nucleotides and sugar nucleotides in embryos of Bufo arenarum at the stages of morula, gastrula, and neurula have been measured. The total amounts of purine nucleoside diphosphates decreased...
Electroporation has led to new approaches to the analysis of gene regulation of the chick embryonic system. However, application of this method to Xenopus, another model organism of embryology, has le...
