Abstract

A mild graft-versus-host reaction induced in (BALB/cJ x DBA/2J) F1 mice by the administration of parental spleen cells that differ at several weak histocompatibility loci did not influence the development of lymphomas in these animals. Rous sarcoma virus also failed to induce tumors in the runt and control animals. Breast carcinomas, presumably due to contamination of the inoculums with mammary tumor virus, occurred in those experimental groups given parental cells, whether or not they were viable or immunologically competent. We found no evidence that the immunologic process—as represented by the graft-versus-host reaction—is causally related to the induction of neoplasia.
