Abstract
Base materials for tissue regeneration which enable the tissue regeneration, have mechanical properties needed in the tissue regeneration and can disappear via degradation in vivo after the completion of the tissue regeneration; and implantable materials with the use of the same. The above-described base materials for tissue regeneration comprise polyrotaxane, wherein biocompatible groups having bulky substituents have been introduced via hydrolyzable bond into both ends of a linear molecule penetrating plural cyclic molecules, or a polyrotaxane hydrogel having a network structure formed by crosslinking the cyclic molecules to each other, the biocompatible groups to each other, or the cyclic molecules to the biocompatible groups in each polyrotaxane molecule.
