| Outline of Final Research Achievements |
In this Fostering Joint International Research, we aimed to establish cell-micro encapsulation methods to prevent immune rejection reactions based on technique using poly(ethylene glycol)-conjugated phospholipid (PEG-lipid). We successfully collaborated with Prof Bo Nilsson in Uppsala University (in Sweden), who has been working with clinical cell transplantation. In this study, we focused on the cellular surface modification to inhibit immune responses which occurred immediately after transplantation, and succeeded in the regulation with PEG-lipids.

| Academic Significance and Societal Importance of the Research Achievements |
糖尿病治療を目的とした膵ランゲルハンス島（膵島）移植、様々な疾患の治療に検討されている間葉系幹細胞（MSC）および腎疾患に対する腎臓移植では、移植直後の炎症反応が原因で、細胞傷害を受けるため、生着率が大きく低下する。そのため、本研究成果は、細胞移植や臓器移植の生着率の向上に大きく寄与するものである。
