| Growth protocol |
Total blood sample (PAXgene tube, PreAnalytiX) was taken at the time of preeclampsia diagnosis (and matched on gestational age at inclusion for controls) and was repeated 4 to 6 weeks postpartum. PAXgene tubes were stored at 4°C for 24 hours, before freezing for 24 hours at -20°C and then permanently stored at -80°C. At-term placental biopsy was also performed at the time of delivery for each of the included women. Placental biopsy was defined as a macroscopically placental area of 2x2 cm including both chorionic and basal membranes. Biopsies were immediately preserved in RNAlater (Thermo Fisher Scientific) for 24 hours at 4°C, before freezing for 24 hours at -20°C, then permanently at -80°C.

total RNA |
| Extraction protocol |
RNAs from total blood samples were extracted using the PAXgene Blood RNA kit according to the procedure recommended by the manufacturer (Qiagen). Briefly, total blood was lyzed using proteinase K and the nucleic acids were precipitated by the addition of ethanol. DNA was digested with DNase I RNase-free for 15 minutes at room temperature. Total RNAs were eluted and then incubated at 65°C for 5 minutes before being placed at -80°C. Total RNAs from placenta biopsies were extracted using the RNeasy Mini Kit according to the procedure recommended by the manufacturer (Qiagen). After dissolution of placental tissue with RLT-β-mercapto-ethanol, nucleic acids were precipitated with the addition of ethanol. DNA was digested with DNase I RNase-free for 15 minutes at room temperature. Total RNAs were eluted before being placed at -80°C. The quality and quantity of the extracted RNAs were evaluated using the Bioanalyzer 2100 (Agilent Technologies) and by NanoDrop Spectrophotometer (Nanodrop Technologies).
