[Localization of the fluorescent portion of the Y-chromosome in interphase nulcei of human embryonic kidney cell cultures].

The localization and frequency of accurrence of Y-chromosome fluorescent bodies in interphase nuclei in the cellular culture of 4-months male and female human embryos, were studied with fluorochromine method with quinacrine dehydrochloride. In cellular cultures of male embryonic kidney the frequency of Y-chromatin was about 50%. The Y-chromosome structural connection with nuclear membrane and nucleolus was demonstrated.
