Bone marrow transplantation Gale has contributed to basic science and clinical research in bone marrow transplantation where he made contributions to understanding the immune-mediated anti-leukemia effects of transplants (graft-versus-leukemia). He has also advanced understanding of other complex immune effects of transplants in humans, like graft-versus-host disease and post-transplant immune deficiency. He has worked on alternate sources of hematopoietic stem cells including fetal liver transplants.
