We studied the influence of factors secreted by the placenta in physiological and preeclampsia-complicated pregnancy on migration activity of endothelial EA.Hy926 cells. It was found that migration of endothelial cells was more intensive in the presence of secretory factors from trimester I placentas in comparison with trimester III placentas and was lower in the presence of placental factors in preeclampsia in comparison with physiological pregnancy.
