ABSTRACT
<p><b>OBJECTIVE</b>To determine the autocrine effect of vascular endothelial growth factor (VEGF) on epidermal keratinocytes HaCaT cells.</p><p><b>METHODS</b>Cultured HaCaT cells were treated with various concentrations of VEGF(165) (0,1,5,10,25,50,100 ng/ml) or Avastin (0,0.063,0.125,0.25,0.50,1.0,2.0 mg/ml) in vitro. HaCaT cell proliferation was determined by MTT assay and the cell migration was measured by migration assay. The effect of VEGF(165) (10 ng/ml) on phosphorylation of ERK1/2 was detected in HaCaT cells pretreated or not pretreated with Avastin (0.5 mg/ml).</p><p><b>RESULTS</b>VEGF enhanced the proliferation and migration of HaCaT cells in a dose-dependent manner, while Avastin inhibited the effects of VEGF also in a dose-dependent manner. VEGF(165) (10 ng/ml) induced the phosphorylation of ERK1/2 in HaCaT cells,but which was blocked by Avastin (0.5 mg/ml).</p><p><b>CONCLUSION</b>VEGF enhanced the proliferation and migration of HaCaT cells in a dose-dependent manner, while Avastin inhibited the effects of VEGF also in a dose-dependent manner.
