[Karyologic study of continuous cell lines. IV. Study of human cell lines using the C-method of staining chromosomes].

With the aid of the C-method of chromosome staining marker chromosomes three classes of human continuous cell lines were studied: 1) HeLa and HeLa-like cell lines (HEp-2, U, KB); 2) non-HeLa cell lines, with type B mobility of glucose-6-phosphate-dehydrogenase (HOS, A-549, A-204); 3) lymphoblastoid cell lines (Raji, Namalva, L-101). Two C-marker chromosomes were observed in two investigated cell lines A-204 and KB, one C-marker chromosome was observed in HEp-2, HeLa, U, A-549, Namalva cell lines; C-markers were absent in HOS and L-101 cell lines. Y-chromosome was found in Raji, A-549 and L-101 cell lines. The C-method of chromosome staining is a simple method, promoting an intraspecific identification of human cell lines.
