An autologous or autograft involves donor skin being taken from another part of the victim’s body. What is known as an isograft, syngraft, or isogeneic graft involves a donor and a victim who are genetically identical. An allogeneic transplant or allograft refers to a graft in which the donor and the victim are of the same species. A xenograft, heterograft, or xenogeneic graft will be between a donor and a victim of different species. With a prosthetic graft, synthetic materials are used to replace lost tissue.
