Keratinocyte Growth Factor (KGF), also known as Fibroblast Growth Factor 7 (FGF7), is a member of the fibroblast growth factor family. It is a potent mitogen specifically for epithelial cells, including keratinocytes, which are the predominant cell type in the epidermis . KGF is produced by mesenchymal cells and acts predominantly in a paracrine manner .
Key Biological Properties: KGF is a small signaling molecule that binds to the fibroblast growth factor receptor 2b (FGFR2b) . It regulates the migration and differentiation of epithelial cells and protects them from various insults under stress conditions .
Expression Patterns and Tissue Distribution: KGF is produced by mesenchymal cells and its receptor, FGFR2-IIIb, is expressed by various epithelial cells, including epidermal keratinocytes, intestinal epithelial cells, and hepatocytes . After acute injury, KGF expression is strongly up-regulated in various tissues, including the skin and bladder .
Primary Biological Functions: KGF plays a crucial role in wound healing by promoting the proliferation, migration, and differentiation of epithelial cells . It also helps in protecting epithelial cells from damage and stress .
Role in Immune Responses and Pathogen Recognition: While KGF’s primary role is in epithelial cell regulation, it indirectly supports immune responses by maintaining the integrity of epithelial barriers, which are the first line of defense against pathogens .
Mechanisms with Other Molecules and Cells: KGF exerts its biological effects by binding to its high-affinity receptor, FGFR2-IIIb . This binding triggers downstream signaling cascades that promote cell proliferation, migration, and differentiation .
Binding Partners and Downstream Signaling Cascades: The interaction between KGF and FGFR2-IIIb activates several downstream signaling pathways, including the MAPK/ERK pathway, which is crucial for cell proliferation and survival .
Regulatory Mechanisms Controlling Expression and Activity: KGF expression is regulated by various factors, including endocrine hormones such as estrogen and LH . These hormones can stimulate KGF gene expression in mesenchymal cells .
Transcriptional Regulation and Post-Translational Modifications: The transcriptional regulation of KGF involves various signaling molecules and pathways that respond to cellular stress and injury . Post-translational modifications, such as phosphorylation, also play a role in modulating KGF activity .
Biomedical Research: KGF is widely studied for its role in epithelial cell biology and wound healing . It is also being evaluated for its potential in treating conditions like oral mucositis resulting from cancer chemoradiotherapy .
Diagnostic Tools and Therapeutic Strategies: KGF has potential applications in developing diagnostic tools for epithelial cell-related conditions and therapeutic strategies for enhancing wound healing and protecting epithelial tissues .
Role Throughout the Life Cycle: KGF plays a vital role throughout the life cycle, from development to aging and disease . During development, it supports the growth and differentiation of epithelial tissues . In adulthood, it helps maintain epithelial integrity and promotes wound healing . In aging and disease, KGF expression can be altered, affecting tissue repair and regeneration .
