Statistical analysis of expression of AnxA1 and Gal-3 for IHC was carried out with the Mann–Whitney U-test (*P < 0.05)

Immunohistochemical staining for AnxA1, 0 = no staining, 1–10% as 1+ , 11–50% as 2+ , 51–70% as 3+ , 71–100% as 4 + . (Numbers in bracket are in the percentage)

STM Syncytiotrophoblast membrane, CVSC chorionic villous stromal cells, VSMC vascular smooth muscle cell, VVEC villous vascular endothelial cells
