Outline of Final Research Achievements |
We isolated and expanded adequate numbers of cells with characteristic features of mesenchymal stem cells (MSCs) from the chorionic plate (CP-MSCs), chorionic villi (CV-MSCs), and decidua basalis (DB-MSCs) of human term placental tissues. All placenta-derived MSCs expressed pregnancy-associated C14MC microRNA (miRNA) (miR-323-3p). Interestingly, the placenta-specific C19MC miRNAs (miR-518b and miR517a) were clearly expressed in CP-MSCs and CV-MSCs of foetal origin. High-efficiency siRNA transfection was confirmed in twice-passaged CV-MSCs with little toxicity, and microarray analysis was used to screen for miR-518b target genes. Subsequently, we determined the reference values for circulating pregnancy-associated placental miRNAs on C19MC in maternal plasma throughout pregnancy. The reference values for circulating pregnancy-associated placental miRNAs in maternal plasma may contribute to the prediction of a preeclampsia before the onset of disease.

Academic Significance and Societal Importance of the Research Achievements |
胎盤由来MSCにおける妊娠関連microRNAと病態形成との詳細な分子機序についてはさらなる研究が必要であるが、胎盤由来MSCを利用することで妊娠関連疾患の分子メカニズムの解明に有用なツールとなりうることが示唆された。そして、母体血漿中の妊娠関連microRNAを定量化することが妊娠高血圧症候群の病態評価につながる可能性が示唆された。本研究の成果は、産科疾患の病態解明ならびに早期診断に貢献すると期待される。
