Abstract
Genetically anemicW/W v mice were cured by marrow allografts from donors of 13 out of 18 tested strains that differed at non-H-2 histocompatibility alleles defined by skin or tumor grafting. They were also cured by donors from all four tested congenic lines whose antigenic differences had been defined by induction of serum antibodies. They were not cured acrossH-2 differences. Tail skin graft survival times on uncuredW/W v recipients were determined for all congenic lines used as marrow donors. The longest and shortest skin graft survival times predicted correctly marrow graft success or failure. NoW/W v mice were cured by marrow grafts from donors of the three congenic lines whose skin grafts were rejected in fewer than three weeks. Almost everyW/W v mouse grafted was cured by marrow grafts from donors of the 13 congenic lines whose skin grafts survived longest, from 11 to more than 25 weeks. Intermediate skin graft survival times failed to predict whether marrow grafts would succeed.W/W v mice were cured by marrow from four congenic lines with mean skin graft survival times of 4.2, 4.4, 8, and 9 weeks, while marrow grafts failed from other congenic lines with mean skin graft survival times of 3.3, 3.4, 4.8, and 8.7 weeks. The simplest explanation for these results is that the antigens specified by theH-2, H-3, H-4, H-25, andH-28 loci are strongly immunogenic on both marrow precursor cells and skin,H-17 andH-24 are strongly immunogenic on skin but not on marrow, andH-12 is strongly immunogenic on marrow precursor cells but less strongly on skin.
