Cytokine expression in placenta-derived mesenchymal stem cells in patients with pre-eclampsia and normal pregnancies

Abstract Objectives: The aim of this study was to investigate the levels of cytokines in placenta-derived mesenchymal stem cells (MSCs) in normal pregnancies and those with pre-eclampsia. Materials and methods: C5a, CD40 Ligand, G-CSF, GM-CSF, GROα, I-309, sICAM-1, IFN-γ, IL-1α, IL-1β, IL-1ra, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-13, IL-16, IL-17, IL-17E, IL-23, IL-27, IL-32α, IP-10, I-TAC, MCP-1, MIF, MIP-1α, MIP-1β, Serpin E1, RANTES, SDF-1, TNFα, and sTREM-1 were measured in mesenchymal stem cells using the human cytokine array panel A. The soluble intracellular adhesion molecule-1 (sICAM-1), stromal-derived factor-1 (SDF-1) and monocyte chemotactic protein-1 (MCP-1) were measured by real-time PCR and confirmed by Western blot analysis. Results: MSCs derived from the deciduas of normal pregnancies had significantly elevated levels of sICAM ( p  = 0.000) and SDF-1 ( p  = 0.011), compared to the pregnancies with pre-eclampsia. The level of MCP-1 in the decidua-derived MSCs was not significantly different. No significant difference was observed between normal and pre-eclamptic pregnancies for the amnion-derived MSCs. Conclusions: The decreased levels of sICAM and SDF-1 found in the decidua-derived MSCs from pre-eclamptic pregnancies might be associated with some of the immunological alterations in pre-eclampsia.
