Keratinocyte Grow th Factor-2 (KGF-2) was originally identified from rat embryos by homology-based

polymerase chain reaction. Human and mouse KGF-2 were subsequently cloned. The human KGF-2 cDNA

encodes a 208 amino acid residue protein with a hydrophobic amino-terminal signal peptide. Human

KGF-2 shares approximately 92% and 95% amino acid sequence identity with mouse and rat KGF-2,

respectively. Among the FGF family members, KGF-2 is most closely related to FGF-7. KGF-2 transcripts

has been shown to be most abundant in the embryo and adult lungs. Recombinant KGF-2 preparations

have been shown to be mitogenic for epithelial and epidermal cells but not fibroblasts. Based on its in

vitro biological activities and in vivo expression pattern, KGF-2 has been proposed to play unique roles

in the brain, in lung development, wound healing and limb bud formation.
