[Marker chromosome study of green monkey cell cultures]

An investigation of three continuous green monkey cell lines by the C-method of differential staining of chromosomes revealed one marker chromosome in BSC-1 cell line and three marker chromosomes in Vero cell line. Two variants of CV1 cell line (I and II) were sharply different both in the modal class and in the marker chromosomes: a great number of chromosomes and two S-marker chromosomes were characteristic of line I CV1; absence of C-marker chromosomes and the peridiploid chromosome set were characteristic of line II CV1. These marker chromosomes are enough stable and may be used for the identification of the given cell lines.
