What does the term autograft refer to?

Autograft specifically refers to a surgical procedure where tissue is transplanted from one part of an individual's body to another part of the same individual. This procedure is often utilized in various medical situations, such as skin grafts for burn victims or reconstructive surgeries, where the biological compatibility of the tissue is critical, as it reduces the risk of rejection.

In contrast to this, transplants from different species (such as xenografts), from a sibling (which would be considered an Allograft, if from a human), or those done using synthetic or artificial materials don’t meet the definition of autograft as they involve either different genetic material or non-biological sources. Therefore, the option identifying a tissue transplant within the same individual highlights the unique advantage of using autograft techniques, which is critical in various medical and surgical applications.
