Allotransplant (allo- meaning "other" in Greek) is the transplantation of cells, tissues, or organs to a recipient from a genetically non-identical donor of the same species.[1] The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts.
It is contrasted with autotransplantation (from one part of the body to another in the same person), syngenic transplantation of isografts (grafts transplanted between two genetically identical individuals) and xenotransplantation (from other species).
Allografts can be referred to as "homostatic" if they are biologically inert when transplanted, such as bone and cartilage.[2]
An immune response against an allograft or xenograft is termed rejection. An allogenic bone marrow transplant can result in an immune attack on the recipient, called graft-versus-host disease.

National Cancer Institute 14, 669: The term homostatic graft might be applied to inert tissues such as bone and cartilage when transferred from one individual to another of the same species; and the term homovital graft might be used in reference to grafts whose cells must continue to grow and reproduce for the graft to be effective after similar transplantation; H. Conway, The Bulletin of the Hong Kong Chinese Medical Association 13, 43: These grafts persist however as homostatic grafts and are completely replaced by host tissues in time.)
