SCID mice inoculated with peripheral blood lymphocytes from a tumor-bearing BLV-positive cow developed lymphosarcomas after 6 months. DNA from the splenic tumor specifically hybridized with a bovine Sstl satellite probe, showing that these tumor cells were of bovine origin. The clonality of the SCID splenic tumor, as measured by the integration pattern of BLV proviruses, was the same as that in the donor lymphocyte population.
