Abstract Background Extravillous trophoblast (EVT) cells play an essential role in the maternal-fetal interaction. Although abnormal development and function of EVT cells, including impaired migration and invasion capability, are believed to be etiologically linked to severe pregnancy disorders including pre-eclampsia (PE), the associated molecular mechanisms are not clear ascribed to the lack of an appropriate cell model in vitro. Cyclosporine A (CsA) is a macrolide immunosuppressant and is also used in clinic to improve pregnancy outcomes. However, whether CsA has any effects on the function of EVT cells has not been well investigated. Methods In this study, we induced differentiation of human induced pluripotent stem cells (hiPSCs) and human embryonic stem cells (hESCs) into EVT cells (hiPSC-EVT and hESC-EVT cells, respectively) by Y27632, NRG1, A83-01 and matrigel, and collected these derived EVT cells by flow cytometry for sorting cells positive for double HLA-G and KRT7, which are EVT markers. We then investigated the effects of CsA on the invasion and migration of these derived EVT cells. Results We found that the hiPSC-EVT and hESC-EVT cells expressed high levels of the EVT markers such as KRT7, ITGA5 and HLA-G but low levels of OCT4, a stem cell marker, and that CsA significantly promoted the invasion and migration of hiPSC-EVT and hESC-EVT cells. Conclusions We successfully generated hiPSC/hESC-derived human EVT cells, which may be applicable for investigating the remodeling process of spiral arteries remodeling and the possible mechanisms of EVT-related diseases in vitro. Furthermore, our findings provide direct evidence that CsA regulates the function of EVT cells and molecular basis by which CsA may be used to treat pregnancy complications in clinic associated with deficient EVT function.
