| Outline of Final Research Achievements |
Evaluation of placental drug transport is the first step in chemotherapeutic safety evaluations during pregnancy, but a well-established in vitro model is not available. Therefore, it is necessary to increase the similarities between the syncytiotrophoblast, the main layer of the placental barrier, and the in vitro evaluation model. We focused on the in vivo similarities of differentiating induced pluripotent stem cells (iPSCs). In this study, the conditions required to differentiate iPSCs into syncytiotrophoblasts, such as retinoic acid (RA), a factor required for the differentiation of hematopoietic stem cells from iPSCs, were investigated using hCG secretion as a marker of syncytiotrophoblasts. We demonstrated that iPSCs differentiate into syncytiotrophoblasts, characterized by marked hCG secretion after RA treatment. Our future studies will involve optimization of the differentiation conditions for iPSC-derived syncytiotrophoblast cell layers by RA.
