Outline of Final Research Achievements |
The purpose of this project is to demonstrate ideal structure and stiffness of scaffolds for osteogenic cells and to develop ideal scaffolds with biodegradable polymer materials. Under regular culture conditions, human periosteal cells (PC) expressed integrin α1β1 and CD44 as major adhesion molecules. Atomospheric plasma treatment modified the titanium surface and facilitated their osteoblastic differentiation. We also found that human platelet-rich fibrin (PRF) extract can be substituted for FBS. As for scaffolding materials, we developed a combinational porous membrane made of polycaprolactone and hydroxyapatite and found its stiffness and microstructure appropriate for PCs.
