| Outline of Final Research Achievements |
We have proved that gene activated matrix (GAM) with non-viral osteogenic plasmid vector has good bone regenerative ability. However, plasmid vector has low gene transfer efficiency. Therefore, new GAM which has good gene transfer efficiency is expected. On the other hand, although viral vectors have high gene transfer efficiency, there is a problem that serious side effects appear. The purpose of this study is to develop a GAM using a highly safe viral vector. To date, no superiority has been observed compared to non-viral vectors, so it is necessary to evaluate the conditions in more detail, such as the concentration and how to incorporate them into the carrier.

| Academic Significance and Societal Importance of the Research Achievements |
本研究においては、BMP2搭載AAVベクターを用いた遺伝子活性化基質の開発を目的としていたが、非ウィルス性ベクターと比較して優位性は認めなかった。
しかしながら、本研究で得られた結果は今後のバイオマテリアル開発においての新たな知見であり、これらの結果に基づき、今後、さらなる骨再生療法の発展を考えることができると考えた。
