Of the microarray shared genes from Fig. 5b, IGFBP6 in decidua type 1 and decidua type 3 cells (Fig. 6a, b), CP in decidua type 3 cells (Fig. 6b), and ANKRD37 in extravillous trophoblasts (Fig. 6d) demonstrated higher expression in early onset preeclampsia bulk tissue than placenta accreta single-cell analysis. Here, IGFBP6 is linked to preeclampsia.
