Outline of Final Research Achievements

Endothelial progenitor cells(EPC) were transplanted into abortion / hypertensive disorder of pregnancy model mice.The results showed that systemic EPC transfusion significantly reduced the rate of miscarriage, and EPCs were frequently observed in the miscarriage placenta.ES-like cells could be established from abortion / hypertensive disorder of pregnancy model mice,. From the ES-like cells and human iPS cells, conditions for inducing differentiation into vascular endothelial progenitor cells could be established. A large amount of vascular endothelial progenitor cells could be generated.

Academic Significance and Societal Importance of the Research Achievements

流産を繰り返し生児獲得が困難な患者自身より、培養した血管内皮前駆細胞を妊娠初期に自家移植すれば、再生医療による流産予防の新たな治療として期待ができる。今回の研究成果は、流産患者や子宮胎盤形成不全症の新たな治療の開発に寄与する可能性がある。
