Transformation of Baboon Cells with Feline Sarcoma Virus

Abstract
Testes cells from two baboons have been transformed by the Snyder-Theilen (ST) and Gardner-Arnstein (GA) strains of feline sarcoma virus (FeSV). The resulting cell cultures formed tumors in immunosuppressed mice, but not in the autologous baboons. The cells transformed by GA FeSV contained more feline gs antigen than those transformed by ST FeSV. Conversely, the cells transformed by ST FeSV produced more type-C virus. Unlike FeSV, which has a predilection for feline cells, the virus from baboon cells transformed by ST FeSV replicated in baboon and beagle embryo cells, but not in feline embryo cells, suggesting that this virus is different from FeSV.
