Abstract: Provided are an injectable tissue adhesive hydrogel including gamma-cyclodextrin (γ-CD). When such an injectable tissue adhesive hydrogel including the γ-CD is used as a skin glue, based on a fact that the γ-CD has a bigger hydrophobic cavity than that of α- and β-CDs, the injectable tissue adhesive hydrogel including the γ-CD has stronger interactions than host-guest interactions. In addition, hydrogen bonding in the injectable tissue adhesive hydrogel including the γ-CD can improve both cohesiveness and adhesiveness of gelatin. The injectable tissue adhesive hydrogel including the γ-CD having excellent cell viability is used for adhesion of a skin incision, to thereby effectively promote tissue regeneration.
