Decidual stromal cells form the largest proportion of maternal cells at the maternal-fetal interface. Our aim was to investigate the role of the pre-eclampsia associated decidual activin receptor, ACVR2A, in regulating trophoblast functions at this interface. St-T1b and HTR-8/SVneo cell lines were used to model decidual stromal and trophoblast cells respectively. St-T1b conditioned medium inhibited HTR-8/SVneo adhesion, proliferation, migration and invasion; all effects that were attenuated by decidual ACVR2A siRNA transfection. These findings suggest that altered decidual ACVR2A expression perturbs the maternal-fetal crosstalk involved in regulating trophoblast function at the interface, which may affect placentation and lead to pre-eclampsia.
蜕膜基质细胞在母胎界面处构成母体细胞的最大比例。我们的目的是研究子痫前期相关的蜕膜激活素受体ACVR2A在调节该界面处滋养层细胞功能中的作用。分别使用St-T1b和HTR-8/SVneo细胞系模拟蜕膜基质细胞和滋养层细胞。St-T1b条件培养基抑制HTR-8/SVneo细胞的黏附、增殖、迁移和侵袭；而蜕膜ACVR2A siRNA转染可减弱所有这些作用。这些发现表明，蜕膜ACVR2A表达的改变扰乱了参与调节界面处滋养层细胞功能的母胎相互作用，这可能影响胎盘形成并导致子痫前期。
