Localisation of DAMPs in term placenta from uncomplicated pregnancies and placental explants cultured under control conditions or exposed to hypoxia (1% O2), oxidative stress (1 mM H2O2) or LPS (1 ng/ml) treatment for 72 h. Representative images from three independent experiments are shown. Immunohistochemistry for: (AD) high mobility group box 1(HMGB1), (EH) S100 calcium binding protein A8 (S100A8), (IL) S100 calcium binding protein A12 (S100A12) and (MP) heat shock protein 70 (HSP70). Black arrow heads indicate representative positive stromal cells, black arrows show representative positive trophoblast cells, v = vessels. Magnification × 200. Scale bar marked on negative controls represents 50 μm.
