Outline of Final Research Achievements

Islets must be isolated and purified using collagenase from a donor pancreas before islet transplantation. Beta-cells might be injured during this process and decrease to produce insulin. Whole islets including not only beta-cells but also alfa-cells are evaluated in traditional method to evaluate islet’s ability. In this research, we isolated beta-cells from islets and directly analyze beta-cell viability using flowcytemetry.

Academic Significance and Societal Importance of the Research Achievements

膵島内のβ細胞viability解析、およびβ細胞含有率測定によりβ細胞そのものを評価することで、膵島移植後のグラフト機能を予測し得る。十分なβ細胞機能を有するかわからないマージナルドナーから摘出した膵臓を膵島分離し、作成したグラフトのβ細胞を評価することにより、膵島移植に適するか、移植前に評価できるようになることが期待され、膵島移植の成績向上に寄与しうる。
