Transformation of Indian muntjac cells by murine and avian sarcoma viruses

Indian muntjac cells were efficiently transformed by murine sarcoma virus (MSV) and avian sarcoma viruses (ASV). When colony formation of the infected cells was examined in soft agar, many colonies were formed by the ASV-injected cells but no colony was seen in the MSV-infected cells. The ASV-transformed cell clones differed among the clones in morphology, presence of inducible ASV genome, and karyotypes.
