| Outline of Final Research Achievements |
In this research, we have aimed to develop injectable hydrogel materials that can be used for rapid bone regeneration. Instead of conventional bone prosthetic materials like inorganic calcium phosphate paste, we have tried to synthesize organic hydrogel materials in which cells can be encapsulated, and that can strongly adhere to inorganic material surfaces such as hydroxy apatite of bone mainly constituent.
First, to promote bone remodeling process, we have synthesized scaffold materials where calcification could easily form. Multiple modification of gelatin materials enables us to successfully prepare injectable hydrogel materials that can be adhere and connected to inorganic glass or hydroxy apatite surfaces, and where calcium deposit can be rapidly formed. We have also confirmed good cell viability when cells were cultured on and within the hydrogel materials.
