[Cells of the neural crest and their derivatives in vertebrates: the mechanisms of migration and its role in tissue formation].
Segregation, determination and migration of the neural crest cells have been considered in the head and trunk of birds and mammals, with special reference to segment-specific migration. The mechanisms of their migration and involvement in formation of some organs are discussed, as well as the model of "catch" of the neural crest cells proposed for explanation of the morphogenetic processes.
