Outline of Final Research Achievements

Mesenchymal stem cells have been reported to be a promising cell source in regenerative medicine. We analyzed secretory factors from amnion-derived mesenchymal stem cells, and identified eicosapentaenoic acid (EPA) and its metabolite resovlin E1 (RvE1).
When we administered EPA to LPS-induced premature birth model rats, it improved premature birth, and the concentrations of EPA and RvE1 in amniotic fluid were recovered. These results suggest that EPA prevents preterm birth via RvE1.

Academic Significance and Societal Importance of the Research Achievements

間葉系幹細胞は再生医療材料として注目されており、その作用機序の解明は重要な課題である。本研究では、羊膜由来間葉系幹細胞から分泌される液性因子の解析から、早産予防に寄与する生理活性脂質であるレゾルビンE1を同定した。エイコサペンタエン酸(EPA)を早産モデルラットに投与することで、EPAならびにその代謝産物であるレゾルビンの羊水中濃度が上昇し、早産が予防された。EPAの投与が早産の予防につながる可能性が示唆された。
