VIP+ EVT cells are associated with SpA remodelling and exocrine glands. (a) Decidua basalis were used to stain with anti‐HLA‐G, anti‐SMA, anti‐CD31, anti‐CD45, or anti‐VIP Abs to explore early (I) or late (II) SpA remodelled. Representative microphotographs of eight decidua basalis are shown. (b) Decidua basalis were stained with anti‐HLA‐G, anti‐SMA, anti‐CD31, anti‐CD14, anti‐CD56, or anti‐VIP Abs to explore maternal glands. The microphotographs were taken with Zeiss Clark microscope with apotometer. The negative controls incubated with the secondary Alexa's Abs (568 and 488 nm) are shown in the panel above. Representative microphotographs of six decidua basalis. Ab: antibody; CD: cluster differentiation; EVT: extravillous trophoblast; HLA‐G: human leukocyte antigen G; SMA: smooth muscle actin; SpA: spiral arterioles; VIP: vasoactive intestinal peptide
