The main ingredient in BFGF is recombinant basic fibroblast growth factor (rb-bFGF) - a multifunctional growth factor with a wide range of bioactivity, which can promote the reparation and regeneration of tissues and cells derived from the mesoderm and ectoderm (such as epithelial cells, dermal cells, fibroblasts, vascular endothelial cells, osteoblasts, nerve cells etc.). The specific combination of rb-bFGF with the wounded target cell surface can trigger the cells to repair actively and promote cell division, proliferation, migration and differentiation, so as to accelerate wound healing and improve the healing quality. It is a safe and effective new drug for wound healing.
