[Comparative study of Y-chromatin and fluorocenters in the interphase nuclei of human cells].

Y-chromatin of nerve cells and fibroblasts in culture has a similar morphofunctional organization. The average number of fluorocentres in the above-mentioned cells is different, i.e.

[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.
