Abstract
Growth factors play an important role in wound healing, and they mainly accelerate wound healing by activating the related signal pathways. Chinese scientists have been conducting basic and clinical researches on growth factors for 30 years, with a series of growth factor drugs being developed and widely used in the treatment of burns and trauma and chronic refractory ulcers. This paper expounds the frontier progress of growth factors on wound healing from the perspectives of immunity, nerve, fat, and so on, and puts forward the further thoughts of the research team on the regulation of wound healing by growth factors.
