PG - C535-43 LID - 10.1152/ajpcell.00310.2008 [doi] AB - Bone marrow stromal cells (BMSCs) are capable of differentiating into multiple cell lineages including endothelial cells. Simvastatin, an HMG-CoA reductase inhibitor that is used as a cholesterol-lowering agent, promotes endothelial differentiation from epithelial progenitor cells (EPC). The Notch signaling pathway, which plays a key role in multiple cell functions such as differentiation, proliferation, and apoptosis, can be regulated by simvastatin. Therefore, we examined the effect of simvastatin on BMSC differentiation into endothelial cells and the underlying mechanisms involved in this process. We observed that simvastatin stimulation of rat BMSCs resulted in significantly increased expression of endothelial-specific genes and proteins, including von Willebrand factor (vWF), CD31, vascular endothelial-cadherin (VE-cadherin), vascular endothelial growth factor receptor-2 (VEGFR2, Flk-1), and VEGF receptor 1 (VEGFR-1, Flt-1). Simvastatin also significantly increased capillary tubelike formation of the BMSCs. In addition, the intracellular cleavage of Notch (NICD) was markedly enhanced by simvastatin in BMSCs. Incubation of BMSCs with a gamma-secretase inhibitor, or Notch1 small interfering RNA (siRNA) that significantly inhibited the formation of NICD, blocked the expression of endothelial-specific markers in BMSCs and their differentiation into functional endothelial cells. These data suggest that simvastatin induces rat BMSCs differentiation into endothelial cells via a Notch signaling pathway.
