[Karyotype change in human cell cultures in the process of the reversion of Coxsackie B virus sensitivity].
The study was done on a subline of cells reverting to sensitivity to Coxsackie B3 virus after treatment of J-41 cells resistant to this virus with a homogenate prepared from the sensitive J-96 cell culture. Cytogenetic examinations of this cell subline showed its karyological characteristics to approach those of the sensitive J-96 culture. The modal number of chromosomes and the number of chromosomes 2, 9, 11, 12, and 21 were completely restored and marker chromosomes typical of the sensitive culture appeared. In the reverted subline there was almost no marker chromosomes peculiar for the resistant J-41 culture. In addition, a decrease in the number of chromosomes 1 and 19 replicas as compared with J-96 and J-41 culture cells and the presence of marker chromosomes not found in the original cultures indicate that this subline has its own distinctive characteristics.
