title: [Cytogenetic and immunological specificity of mammalian hybrid cell lines].
abstract: Karyotypes of the hybrid cell lines NS-RL-3 (TK- -sheep kidney cells and rabbit lymphocytes) and betaCR-NS (TK- -rabbit beta-cells and TK- -sheep kidney cells) were investigated. It was shown that both hybrid cell lines were characterized by presence of both sheep and rabbit chromosomes, which number and structure varies depending on the cell type and the number of passages. In some cases the aberrant chromosomes were identified. It was observed, that 40-50% of the NS-RL-3 cells survived in culture in the presence of the human blood serum, and also were identified during 7-28 days after their introduction into the organism of the animal. Thus, the partial immunological tolerance of the hybrid cell lines has been suggested.
