Outline of Final Research Achievements

We conducted this research to develop novel therapy for preterm labor and neonatal brain and lung complication associated with intra-amniotic inflammation.
We isolated mesenchymeal stem cells from umbilical cords and placentae that could be collected by non-invasive procedure without ethical problem. We also adjusted the isolation method to get high quality cells. Umbilical cords derived mesenchymeal stem cells and chorionic villi derived mesenchymeal stem cells were used in this study because they were considered to suitable cells in clinical use. In the other hand, we established novel animal model of preterm labor and neonatal complications associated with intra-amniotic inflammation. Then assessed therapeutic efficacy of mesenchymal stem cells in these conditions. We demonstrated that mesenchymal stem cells could ameliorate local inflammation in the preterm labor model.
