[Comparative study of Y-chromatin and fluorocenters in the interphase nuclei of human cells]. / Sravnitel'noe izuchenie Y-khromatina i fluorotsentrov v interfaznykh iadrakh kletok cheloveka.

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. the number of fluorocentres in neurons is less than that in fibroblasts. The fluorescence intensity of fluorocentres does not depend upon the body size. The data of a comparative study of Y-chromatin permit two classes of bodies to be distinguished depending on fluorescence density and their size.
