[The cytogenetic study of established Syrian hamster cell lines. III. An analysis of the NOR-marker chromosomes in Syrian hamster cell cultures by using differential chromosome Ag-->G restaining].
Using silver staining --> G-banding restaining procedure it was found that the Syrian hamster chromosomes had nucleolar organizers on subtelocentric chromosomes 2, 6, 9, 10 and 13, and on acrocentric chromosomes 16, 17 and 19. In this case, NORs may be recognized only on one of homologous chromosomes, and no more than 9 NO-chromosomes may be found in one metaphase plate. In HaK, BHK-21 (C-13) BKK and BHK-21 (C-13) C cell lines, chromosomes 6, 9, 16, 17 and 19 have NORs, and in each line there are specific marker chromosomes with NOR. The markers consist of the material of chromosomes 6, 9, 16 and 17, with only chromosomes 16 and 17 being incorporated into rearrangements by their NORs. The silver staining --> G-banding restaining procedure makes possible not only identification of NO-chromosomes, but also refinement of the marker origins.
