Outline of Final Research Achievements

In this study, our aim was that we evaluated whether the transplantation of mesenchymal stem cells overexpressing HMGB1 protein, which played a important role in the cell therapy to heart failure, had a therapeutic effect for heart failure model rats or not. we, however, failed to establish overexpressing HMGB1 protein to mesenchymal stem cells. Therefore, we could not achieve our aim in this study.

Academic Significance and Societal Importance of the Research Achievements

本研究の仮説通りに、HMGB1タンパクを過剰に分泌するように遺伝子操作をした間葉系幹細胞が心不全を起こした心臓に移植されて、心機能の改善等の治療効果があったのならば、現在の心不全に対する幹細胞治療をもっと効果的な標準的な治療法として今後確立させることに役立てると思われる。
