An allograft is a type of tissue transplant where cells, tissues, or organs are taken from one individual and transplanted into another individual of the same species. This procedure is commonly used in medical treatments, such as in orthopedic surgeries for repairing damaged joints or in organ transplants. The donor and recipient are usually not genetically identical, which can lead to complications like rejection. Allografts can come from living donors or deceased donors. To minimize the risk of rejection, doctors often use immunosuppressive medications to help the recipient's body accept the new tissue. Successful allografts can significantly improve the quality of life for patients needing transplants.
