An<unk>  or allogeneic transplant or homograft is a transplant in which transplanted cells, tissues, or organs are sourced from a genetically non-identical member of the same species. Most human tissue and organ transplants are<unk> s.
In contrast, a transplant from another species is called a xenograft. When a transplanted organ or tissue from a genetically identical donor, i.e., an identical twin, is termed an isograft.  Finally, when a tissue is transplanted from one site to another on the same patient, it is termed an autograft.<unk> s and xenografts will be recognised by the recipient's immune system as foreign and will therefore be attacked in a process termed rejection. This does not occur in autografts or true isografts, although in practice, transplants between identical twins are usually covered with immunosuppressants in case they are not 100% genetically identical.
