Genetics of F1 hybrid susceptibility to myeloma grafts.
The genetics of hybrid susceptibility of parental myeloma transplants in histocompatible F1 hybrids was investigated. Various inbred mouse strains and their descendant congenic lines were crossed with BALB/C mice to produce appropriate F1 hybrids. Genetic inferences were drawn from the comparison of the frequencies of tumor graft takes among congenic combinations. Hybrids containing the C57BL/10 genetic background were less susceptible to myeloma transplants than were hybrids of other genotypes. Both H-2-associated and non-H-2-associated genetic factors played significant roles in determining host susceptibility to the transplants. The D end of the major histocompatibility complex did not play a predominant role in determining hybrid susceptibility in C57BL-derived F1 hybrids.
