Professional background

Professor Stephen Mackinnon leads the bone marrow and stem cell program at University College London. He attended medical school at the University of Glasgow. He subsequently trained in internal medicine and haemato-oncology in Glasgow. This was followed by a transplant fellowship at the Hammersmith Hospital in London where he developed an interest in graft-versus-leukaemia reactions.

In 1990 he moved to Memorial Sloan Kettering Cancer Center in New York to continue this work in both the clinic and the lab. He made the use of donor lymphocytes less toxic by limiting the T cell dose administered to transplant recipients allowing separation of graft-versus-leukaemia responses from graft-versus-host disease.

In 1995 he returned to London to his current position. In recent years he has developed an interest novel conditioning regimens. Current research interests include adoptive immunotherapy and immune reconstitution following allogeneic stem cell transplantation. The program has world class transplant outcomes for patients with leukaemia and lymphoma.
