DECELLULARIZED TISSUE

The present invention addresses the problem of providing a decellularized tissue having excellent cell adhesion properties. Provided is a decellularized tissue prepared by decellularizing a biological tissue, said decellularized tissue being characterized in that the ratio of endothermic energy amount, in terms of dry mass, of the decellularized tissue to the biological tissue before the decellularization is 0.70 or greater when measured by differential scanning calorimetry. The ratio by mass of DNA amount, in terms of dry mass, of the decellularized tissue to the biological tissue before the decellularization may be 0.300 or smaller.
