【Task】 This invention makes it a subject to provide the tissue for transplant which solved the problem in transplantation, such as calcification. [Solution] The present inventors have found that by including a biocompatible polymer in an untreated tissue and exposing it to γ-ray irradiation, the tissue was unexpectedly strengthened and calcification was suppressed, and the above problem Solved. Conventionally, it has been recognized that decellularization of a living tissue is a point for suppressing calcification, but it has been shown by the present invention that an effect more than decellularization can be achieved even by γ-ray irradiation.
