title: [Polymorphism of a population of tumor cells and selective processes. I. Ehrlich-IChPh ascitic strain tumor cell subpopulation].
abstract: 4 types of marker chromosomes and of their combination in mouse ascite Ehrlich-I. Ch. Ph. tumor cells are described. Two most frequently encountered subpopulations of cells are found in the tumor: one--with A+B+2C and A+D+2D markers, and the other--with A1+A2+2B+D1+C markers. The former population dominated during 8 days, to be gradually substituted with the former subpopulation. Changes in the number of cells with certain chromosome number in the near-diploid and near-tetraploid cell zones were followed within one passage.
