Autologous transplantation is defined as a transplant where tissue is taken from and returned to the same individual. Which word best describes this type of graft?

• A. Allograft
• B. Autograft
• C. Isograft
• D. Xenograft

Answer: (B)

Tissue moved within the same person is called an autograft. The donor and recipient are the same individual, so the immune system recognizes the tissue as self, minimizing or eliminating rejection. This contrasts with other terms: an allograft comes from a different person of the same species, an isograft from an identical twin, and a xenograft from a different species. Therefore, autograft best describes a graft where tissue is taken from and returned to the same individual.
