Autotransplantation
（重定向自Autologous blood transfusion）
Autotransplantation is the transplantation of organs, tissues, or even particular proteins from one part of the body to another in the same person (auto- = "self-"). The autologous tissue (also called autogenous, autogeneic, or autogenic tissue) transplanted by such a procedure is called an autograft or autotransplant. It is contrasted with allotransplantation (from other individual of same species) and xenotransplantation (from other species). A common example is the removal of a piece of bone (usually from the hip) and its being ground into a paste for the reconstruction of another portion of bone.
