Background: KGF/FGF-7

Keratinocyte Growth Factor (KGF), or Fibroblast Growth Factor-7 (FGF-7), is an important component in many cell culture protocols. It is widely used to promote the growth and differentiation of epithelial cells, including skin keratinocytes, and lung, corneal, and intestinal epithelia. It is a part of tissue engineering and organoid culture protocols, where it can enhance the generation of complex tissues such as liver, gastrointestinal tract, lung, and mammary gland. Furthermore, KGF/FGF-7 has been shown to stimulate the proliferation of pancreatic endocrine progenitor cells and promote their differentiation into mature insulin-secreting beta cells. In these capacities KGF/FGF-7 has significant clinical relevance in studies to better understand gastrointestinal disorders, wound healing, respiratory disease, and diabetes.
