VEGF production in bovine aortic endothelial cells (ECs) measured by Western blot (inset). Shown are VEGF levels after 6 hours of serum starvation. Equal amount of proteins were verified by blotting for actin. Quantification of western blot from all experiments demonstrated that hFN was able to increase VEGF production (* = p < 0.05 vs Basal), while after c(RGDf[NMe]V) or RGDechiHCit treatment VEGF levels returned to basal conditions (# = p < 0.05 vs hFN). All data derived from three different experiments performed in duplicate. The results were expressed as fold increased with respect to the basal condition in untreated samples. Error bars show SEM.
