VEGF expression and in vitro angiogenesis assay of endothelial cells. (A): mRNA expression levels of VEGF at days 3, 7, 14, and 21. (B): Protein expression levels of VEGF at days 3, 7, 14, and 21. (C): Optical images of endothelial cells cultured on matrigel in the presence of the supernatant from Control, Lenti‐LacZ, and Lenti‐PDGF group for 12 hours. (D): The tube‐like numbers of each group (**, p < .01). Scale bar, 100 μm. Abbreviations: PDGF, platelet‐derived growth factor; VEGF, vascular endothelial growth factor.
