Role of cytokines of stem cell secretions in hair regeneration. A VEGF contributes to more perifollicular vascularization in the anagen phase and less in perifollicular vascularization in the telogen phase thus restoring hair. B, C IGFBP1 and hepatocyte growth factor induce hair regeneration through increasing beta-catenin expression. D Role of PDGF in hair regeneration by elevating Shh and LEF1
