Animal-free Recombinant Human FGF-7 (KGF) is expressed in human 293 cells as a monomeric glycoprotein with an apparent molecular mass of 17 and 30 kDa. FGF-7 appears to act on epithelial cells. It also seems to motivate and stimulate proliferation, migration, and differentiation of these cells. It plays a significant role in development, morphogenesis, wound healing, angiogenesis, and tumorigenesis. This cytokine is produced in a human cell expression system with serum-free, chemically defined media. Authentic glycosylation contributes to stability in cell growth media and other applications.
