Effect of Factors Secreted by the Placenta on Phenotype of THP-1 Cells Cultured on a 3D Scaffold.

We studied the effects of secretory products of the placenta obtained from women with normal pregnancy and preeclampsia on the expression of surface markers by THP-1 cells cultured on a 3D Matrigel scaffold. Secretory products of third trimester placentas obtained from women with normal pregnancy reduced the relative number of THP-1 cells expressing CD54 and CD14 molecules and expression of CD14 and CD95 molecules by THP-1 cells in comparison with the effect of secretory products first trimester placentas. In parallel, the intensity of CD49d expression by THP-1 cells increased in the presence of secretory products of third trimester placentas in comparison with the first trimester.
