The SPbMU bone marrow donor database need your help to continue their life-saving research in blood and marrow transplantation for the treatment of leukaemia, immunodeficiency, lymphoma, anemia, neuroblastoma, metabolic disorders and other life threatening diseases. We are proud of the support we receive from the Stefan Morsch Stiftung, European Institute for Research and Development of Transplantation Strategies. However, private contributions are essential for the donor bank to continue the work. We invite you to participate as a contributor in the donor program.
