Growth factors	Clinical application
Vascular endothelial growth factor (VEGF)	Regeneration of epithelial tissue repair, treatment of peptic ulcer (Niu et al., 2019)
Fibroblast growth factor (FGF)	Bone repair, angiogenesis, nerve growth, treatment of chronic complications of diabetes (Figueroa et al., 2019)
Hepatocyte growth factor (HGF)	Chronic liver injury repair, stimulate angiogenesis HGF participate in angiogenesis, morphology, organogenesis, bone restructuring, nerve induction (Vanderwerff et al., 2019)
Insulin-like growth factor (IGF)	cell differentiation, proliferation, individual growth and development (Mancarella et al., 2016)
Transforming growth factor (TGF)	the growth, differentiation, apoptosis and immune regulation of many kinds of cells (Onodera et al., 2019)
Nerve growth factor (NGF)	The treatment effect of neurodegenerative disease is especially remarkable, which is also used to speed burn recovery and reduce the side effects of chemotherapy and radiation (Aloe et al., 2016)
