[Characteristics of human-mouse hybrid cell lines and the changes induced in them by the poliomyelitis virus].
Cells of the four hybrid lines between continuous mouse cells Rag and human diploid embryonal fibroblasts were polymorphic and had mitotic activity in fully formed monolayers. Most of the these mitoses were pathological. Hybrid cells examined 8 months after hybridization were susceptible to the poliomyelitis virus infection with partial cytopathologic effect, they produced virus antigens and the infectious virus. Small hybrid cells displayed a more pronounced cytopathologic effect than did big, polynuclear and mitotic cells. Hybrid cells that were passaged 1.5 months after infection did not excrete any infectious poliovirus but contained poliovirus antigens.
