Dr. Wagner’s research has focused on the development of new treatment approaches for life-threatening diseases for which conventional treatments are unsatisfactory. Dr. Wagner is recognized for pioneering the use of double umbilical cord blood transplantation in adults and embryo selection to insure an HLA matched, healthy child (‘savior sibling’) for another child in need of transplant. He is also a leader in the use of regulatory T cells to prevent rejection and graft versus host disease, expanded blood forming stem cells to speed blood and marrow recovery, novel conditioning regimens to dramatically increase the chance of cure of patients with Fanconi anemia and bone marrow derived stem cells to repair the skin in severely affected children with Epidermolysis Bullosa.
