What is allogeneic?

Allogeneic refers to cells, tissues, or organs that are derived from a genetically different individual of the same species. This term is commonly used in the context of transplantation, where allogeneic grafts are taken from a donor and transplanted into a recipient. Such procedures often require careful matching and immunosuppressive therapy to prevent rejection by the recipient's immune system. Allogeneic stem cell transplants, for example, are used to treat various blood disorders and cancers.
