Allografts

An allograft is a tissue or organ transplanted from one person to another within the same species. For example, a skin graft from a donor to a recipient. Allografts are commonly used in surgeries such as bone repairs, heart valves, and skin replacements. To reduce rejection, the donor tissue is typically processed and matched to the recipient’s tissue type. While the recipient’s immune system may recognize the allograft as foreign, medications called immunosuppressants help prevent rejection. Allografts are valuable when an autograft (using the patient's own tissue) isn't possible or sufficient.
