title: [Acetylcholinesterase in the cells of the neural germ of the chick embryo].
abstract: Activity of AChE in separate cells of the neural tube and ganglionic plate (neural crest) is detected histochemically in chick embryos after 36, 48, 60 and 74 h of incubation, before any specific morphological signs characteristic for the neuroblast appear in them. It is stated that biochemical determination, formation of acetylcholine system coinsides with the proneuroblast phase. The product of the reaction for AChE is a marker which helps to observe migration of proneuroblasts in embryos at early stages of development.
