Outline of Research at the Start

本研究では未分化の前骨芽細胞と分化した骨芽細胞が発現するエクソソームを回収し、未分化を維持する候補タンパク質の探索を目的としている。そのため人工的な微小重力環境における未分化細胞の挙動の詳細を細胞が放出するエクソソーム を調べることで細胞の分化度を調整できる創薬につながると期待した。

Outline of Final Research Achievements

In this study, we aimed to control osteoblast differentiation under microgravity by examining gene expression and calcium deposition in mouse osteoblast-like cells, KUSA, using Alizarin Red staining, and to develop a bone filler that combines osteoblasts with a 3D collagen scaffold created using a 3D printer in a bone defect state. As a result, we were able to control cell differentiation in a microgravity environment and achieve research that will lead to the development of a 3D collagen scaffold.

Academic Significance and Societal Importance of the Research Achievements

本研究成果によって、重力と骨芽細胞の分化機構の詳細が明らかになることによってこれまで人工的に薬剤で分化制御を行なってきたが、重力による細胞自身の分化制御機構を利用することによって骨粗鬆症や骨折後の治癒促進剤の新規創薬に繋がる。
