Presence of allograft-rejection resistance in simian virus 40-transformed hamster cells and its possible role in tumor development.
LSH Syrian hamster cells transformed in vitro by simian virus 40, which is oncogenic for hamsters, are resistant to rejection by adult allogeneic CB hamsters. In contrast, simian virus 40-transformed cells from other species are usually not oncogenic in immunocompetent autologous or isologous hosts. The ability of simian virus 40 to convey resistance to an allograft-type host response to transformed hamster cells may be important in determining the tumor-inducing capacity of these cells and could, in part, explain the species-specific oncogenicity of this virus.
