While I understand that this avoids the extra surgical area as with the autograft, the risk of disease trumps this for me. A graft refers to the piece that is removed from the donor and given to the recipient. *To understand the immunologic mechanisms of hyperacute, acute and chronic graft rejection* 4. Allograft: A graft between genetically dissimilar members of the same species i.e. Types of grafts: The following terms indicate different types of transplants: Autograft: In this type of graft, the tissue is transferred from one body site to another in the same individual. Autograft or autologous graft: skin obtained from the patient’s own donor site. The autograft is the patient’s own bone.

Xenograft (pronounces “zeeno” – graft) An xenograft is a bone graft material made from another species such as cow bone, also called bovine…or pig, also called porcine. Depending on the origin:. If tissues are transplanted from one area on an individual to another area on the same individual (e.g., a skin graft on a burn patient), it is known as an autograft.
