ALLOTRANSPLANTATION

[noun]

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 or allogeneic transplant or homograft. Most human tissue and organ transplants are allografts.In contrast, a transplant from another species is a xenograft. A transplanted organ or tissue from a genetically identical donor (such as an identical twin) is an isograft.
