Zhang et al. found that baicalin, the major component found in the root of the traditional Chinese herb Scutellaria baicalensis, which is used to treat stroke, could promote VEGF expression in HUVECs and human fibroblast MRC-5 cell lines, suggesting the possibility of using baicalin to induce therapeutic angiogenesis in PAD 167. The gene discussed is VEGFA; the disease is peripheral arterial disease.
