| Outline of Final Research Achievements |
In this study, we show a concept for utilizing cells and their functions from the viewpoint of materials science. In particular, we develop cell cross-linked living bulk hydrogels by bioorthogonal click cross-linking reactions of azide-modified mammalian cells with alkyne-modified biocompatible polymers. Importantly, we demonstrate the unique functionalities of the living hydrogels, originating from the basic functions of the cells incorporated in the living hydrogels as active cross-linking points. Moreover, we demonstrate potential application of the cell cross-linked hydrogels as injectable gels for tissue engineering. As this method can be applied to bacteria and viruses because their surfaces can be modified by metabolic glycoengineering, the findings of this study provide a promising route to the generation of living cell-based next-generation innovative materials, technologies, and medicines.
