Mesenchymal Stem Cell-Conditioned Media Modulate HUVEC Response to HO: Impact on Gene Expression and Potential for Atherosclerosis Intervention.

We studied the potential of human bone marrow-derived mesenchymal stem cell conditioned media (hBMSC CM) in protecting endothelial cell properties (viability, proliferation, and migrations) from the deleterious effects produced by the inflammatory environment of HO. Additionally, we investigated their impact on the endothelial cells' gene expression of some inflammatory-related genes, namely, TGF-1, FOS, ATF3, RAF-1, and SMAD3. Human umbilical vein endothelial cells (HUVECs) were cultured individually under three conditions: alone, with varying concentrations of HO, or with varying concentrations of HO and hBMSC CM.
