What are isograft and xenograft?
Isograft refers to tissue transplanted between genetically identical twins. An allograft (termed homograft in older texts) is tissue transplanted between unrelated individuals of the same species. A xenograft (termed heterograft in older texts) is tissue transplanted between individuals of different species.
