Fig. 1: EPC, TNF-α, miR-31, and miR-155 levels in healthy pregnant women and preeclamptic patients.

a The levels of circulating CD34+/KDR+ EPCs in peripheral blood from healthy pregnant (HP) and preeclamptic women (PE). b, c The levels of TNF-α, miR-31, and miR-155 in serum from healthy controls and preeclamptic women. d The levels of miR-31 and miR-155 in PBMNCs from healthy and preeclamptic subjects. n = 12 per group, ***P < 0.001.
