ASP-3 reduced VEGFR2 phosphorylation in HepG2 cells. Immunofluorescence staining was used to evaluate the distribution of VEGFR2 phosphorylation. They were stained with DAPI (blue), fluorescent secondary antibody of phospho-VEGFR2 VEGFR2 (green), and phalloidin (red), respectively. The immunofluorescence profile was visualized under a confocal fluoresce (scale bar: 20 µm).
