Organ Transplantation and Artificial Organs

Allotransplantation

Allotransplant is the transplantation of cells, tissues, or organs, to a recipient from a genetically non-identical donor of the same species. The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts. It is contrasted with autotransplantation, syngeneic transplantation  and xenotransplantation. Allografts can be referred to as homostatic if they are biologically inert when transplanted, such as bone and cartilage. An immune response against an allograft or xenograft is termed rejection. An allogenic bone marrow transplant can result in an immune attack, called graft-versus-host disease.
