An allograft 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. [ [http://www.ehealthmd.com/library/acltears/ACL_surgery.html#allograft Surgery For ACL Tears ] ] Most human tissue and
organ transplants are allografts.
In contrast, a transplant from another species is called a
xenograft. 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.
When a host mounts an immune response against an allograft or xenograft, the process is termed rejection.
A variety of tissue and organs types can be used for allografts. These include:
bone marrow transplants
