Autologous tissue or cells are tissue or cells derived from the same individual. For example, skin transferred from one part of the body to another is autologous tissue in advanced therapies, stem cells are removed, stored, and later given back to the same person. Autologous transplants are used to treat a number of different blood cancers. Autologous stem cell transplantation is distinguished from allogeneic stem cell transplantation, where the donor and the recipient of the transplanted stem cells are different people.
