Abstract	Fibroblast growth factor (FGF) -10 is a new member of the FGF family initially reported in Japan. It is mainly synthesized by mesenchymal cells and acts on epithelial cells in a paracrine manner. FGF-10 actions are dependent on their binding to the iiib form of FGF receptor 2 (FGFR2) iiib, also known as keratinocyte growth factor receptor (KGFR). FGF-10 has high amino acid homology to keratinocyte growth factor (KGF) and plays an important role in fetal limb and lung development and skin wound healing. In the present study, the expression of FGF-10 and FGFR2 iiib messenger RNA (mRNA) in two different human uterine cervical cancer cell lines (CaSki and ME-180) were examined. Both CaSki and ME-180 cells expressed FGFR2 iiib mRNA, while only CaSki cells expressed FGF-10 mRNA and protein. Recombinant FGF-10 (1 ng/ml) increased the growth rate of ME-180 cells and also enhanced mitogen-activated protein kinase (MAPK) phosphorylation of the cells. These data indicate that FGF-10 may directly promote the growth of squamous cell cancer in the uterine cervix via the MAPK pathway.
