title: Evolution of primary tumors induced in adult mice by MSV-H and MSV-H producer tumor cells.
abstract: The oncogenic activity of both MSV-H and MSV-H-producer tumor cells (3T3 + MSV-H) in adult mice was investigated and compared. A higher incidence of tumors was observed with MSV-H tumor cells, especially with very small tumor cell doses. No regression was observed in any of the induced tumors.
