Figure 3From: Small molecule receptor tyrosine kinase inhibitor of platelet-derived growth factor signaling (SU9518) modifies radiation response in fibroblasts and endothelial cellsProliferation assay of HDMVECs. Endothelial cells were plated in collagen I-coated flask and stimulated with 10 ng/ml PDGF (black line) or 2 ng/ml VEGF + 4 ng/ml bFGF (red line) in the absence or presence of SU9518 with increasing concentration (0.1, 0.5, 1, 2 and 5 μM). 72 hours later cells were counted and normalized to respective controls without SU9518.Back to article page
