Abstract

Nitric oxide (NO), as a signaling molecule in vivo, plays an important regulatory role in a variety of physiological and pathological conditions. Mesenchymal stem cells (MSCs) are pluripotent progenitors that can differentiate into a variety of cell types. Vascular endothelial growth factor (VEGF) induces MSC differentiation towards endothelial cells (ECs). Although nitric oxide signaling promotes differentiation and maturation of endothelial progenitor cells, its role in endothelial differentiation of mesenchymal stem cells (MSCs) remains controversial. Frist, cellular proliferation was tested in MSCs treated with/without NO donors S-Nitrosoglutathione (GSNO) or Sodium Nitroprusside (SNP) by MTT assay. Next, after MSCs were cultured with different concentrations of NO donors in the presence of VEGF for 7 days, the cellular morphology was observed under phase microscope and the level of endothelial cell markers fms-like tyrosine kinase (Flt-1) was detected by RT-PCR and immunocytochemistry. The results determined that NO donors (1-200?mol/mL) had no effect on the survival of MSCs. VEGF-treated MSCs exhibited an endothelial-like phenotype, while NO donors-treated cells still have a spindle-shaped phenotype like MSCs. VEGF treatment increased Flt-1 expression, whereas NO donors inhibited VEGF-induced Flt-1 expression. Our Results suggested that NO could inhibit endothelial differentiation of mesenchymal stem cells.
