Human bone mesenchymal stem cells (hMSCs) can differentiate into endothelial cells (ECs), so we aimed to investigate whether hMSCs could also differentiate into a specific arterial or venous ECs. hMSCs were induced to differentiate into ECs using vascular endothelial growth factor (VEGF). Low VEGF concentration (50 ng/ml) upregulated the venous marker gene EphB4, however high concentration (100 ng/ml) upregulated the arterial marker genes ephrinB2, Dll4 and Notch4, and downregulated the venous marker genes EphB4 and COUP-TFll. This VEGF dose-dependent induction was largely blocked by inhibition of the Notch pathway in hMSCs treated with γ-secretase inhibitor. Therefore, differentiation of hMSCs into arterial- or venous-specific ECs depends on VEGF and is regulated by the Notch pathway.
