title: Cytochemical evidence for stage-specific changes of nuclear RNA and nonhistone protein content during early development of Triturus vulgaris.
abstract: During early embryogenesis of Triturus vulgaris, RNA and nonhistone protein contents of neuroectoderm nuclei change with stage specifically. Maximum values were found in the late gastrula after embryonic induction, and in the late neurula with the formation of the neural tube. The stage-specific increases of RNA and nonhistone protein are correlated with a preceding increase of Feulgen-DNA content.
