title: [Ultrastructure of the cells of the neural crest].
abstract: Ultrastructure of the neural crest cells (NCC) has been studied in 9-day-old white rat embryos. Mechanisms, determining the amount of the NCC that get out of the neuroepithelium of the nervous tube have been discussed. By means of ruthenium red components of the extracellular matrix are demonstrated in the area where the NCC get out and in the ventromedial pathway of migration. Certain peculiarities of ruthenium red fixation by the cells are presented.
