PROCÉDÉ DE PRODUCTION DE MATÉRIAU DÉCELLULARISÉ POUR TRANSPLANTATION ET COMPOSITION DE GREFFE COMPRENANT UN MATÉRIAU BIOCOMPATIBLE COMPRENANT LEDIT MATÉRIAU
The present invention has an object to provide a method of producing a decellularized transplantation material that can be used for a graft composition and that minimizes the portion sutured with thread.To achieve this purpose, the present invention provides a method of producing a decellularized transplantation material, wherein the method includes the steps of (a) harvesting a branch-bearing blood vessel from a vertebrate animal (a donor); (b) decellularizing the blood vessel; and (c) adhering, by a protein denaturation treatment, a portion where a branch has been excised to close the vessel. The present invention also provides a graft composition consisting of a biocompatible material that contains the decellularized transplantation material.
