Long-term survival of murine allogeneic bone marrow chimeras: effect of anti-lymphocyte serum and bone marrow dose

Graft-vs-host disease (GVHD) and failure of donor stem cells to engraft permanently are two major obstacles to successful bone marrow transplantation. The effect of a single large dose of anti-lymphocyte serum (ALS) on mice receiving various numbers of H-2 incompatible bone marrow cells was evaluated. Most animals receiving lethal total body irradiation (TBI) and allogeneic marrow died within 45 days due to GVHD. Mice that were given ALS 6 to 24 h before TBI and bone marrow 24 h after irradiation survived in good health for more than 200 days. These cell preparations caused lethal GVHD in third party mice indicating that the lack of alloreactivity was specific to the strain in which the unresponsiveness was originally induced.
