Abstract: The purpose of the present invention is to provide a method for producing a decellularized material for transplantation that can be used in a graft composition and minimizes the portion sutured by thread. To achieve the above purpose, the present invention provides a method for producing a decellularized material for transplantation that includes (a) a step for collecting a branched blood vessel from a vertebrate animal (donor), (b) a step for decellularizing the blood vessel, and (c) a step for adhering the portion from which the branch has been excised by protein denaturation treatment and closing the vessel. The present invention also provides a graft composition comprising a biocompatible material that includes the decellularized material for transplantation.
