Biopsy specimens were classified as "normal histology" if the histological features of the normal human placental bed (endovascular trophoblast invasion in decidual and myometrial segment, normal spiral artery appearance) were documented or "abnormal placental histology" if there were inadequate response to placentation, acute atherosis, increased extravillous trophoblasts, and thrombosis or luminal obliteration of spiral arteries.
They created an in vitro culture of two key cell types involved in spiral artery development - endothelial cells and trophoblasts and then exposed some to serum from women with normal pregnancies and some to preeclampsia serum from women taken at various stages of their pregnancies.
