Epidermal growth factor (EGF) and hepatocyte growth factor (HGF) derived from the human amniotic mesenchymal stem cells (hAMSCs) were higher than other growth factors. HGF and EGF derived from the hAMSCs exhibited a higher level of secretion than other growth factors. All the experiments were repeated three times; error bars indicate SD.
