title: [Dynamics of changes in human cells with chromosome and genetic mutations in prolonged cultivation in a stationary phase. Report 1. Study of cells in xeroderma pigmentosum].
abstract: Ontogenetic changes of normal diploid cells and cells with genetic mutations (LHC-484 from a patient with xeroderma pigmentosum) have been studied under prolonged cultivation in a stationary phase. While investigating the dynamics of complex changes in certain cell properties and cell populations it was found that the cultivated human cells possess a particular pattern of ontogenetic changes for every culture and the dynamics of these changes depends upon the density of the cell population. Two cell subpopulations different in the degree of nucleus heterochromotinization have been discovered.
