The puφose of this study was to evaluate the role of EGF(Epidermal Growth Factor), EGFR(Epidermal Growth Factor Receptor), aFGF(acidic Fibroblast Growth Factor or FGF-1), bFGF(basic Fibroblast Growth Factor or FGF-2), FGFR(Fibroblast Growth Faαor Receptor), and VEGF(Vascular Endothelial Growth Factor) in the development of the human ameloblastomas For this study 9 subjects, diagnosed as ameloblastomas referred to the Dept. of Oral Path. College of Dentistry, Kyung Hee University, 2 subjeαs of normal oral mucosa with any inflammatory changes were used as experimental, control groups respectively. All the tissues ; experimental and control group were fixed in 10% neutral formalin solution and embedded in paraffm, serial tissue section were made 하1m in thickness and processed in the standard way for immunohistochemical method, using primary and secondary antibodies, for EGF(Antirabbit Ig G, rabbit kit at }:1oo dilution), EGFR(Antimouse Ig G, mouse kit at 1:100 dilution), aFGF(Antirabbit Ig G, rabbit kit at 1:100 dilution), bFGF(Antirabbit Ig G, rabbit kit at 1:100 dilution), FGFR(Antimouse Ig G, mouse kit at 1:100 dilution) , and VEGF(Antirabbit Ig G, rabbit kit at 1:100 dilution), all BioGenex U.S. A. made, followed by the Streptavidin - Horse Radish Peroxidase(InnoGenex, Human-avidin kit) appli때on ， counter stained with Mayer’s hematoxylin stain method. And examined under the biologic microscope, graded -(no epithelial stain), +(weak or focal epithelial stain), ++(moderate or focal intensive epithelial stain), +++(intense generalized epithelial staining) for the epithelial, and connective 따sue component in ameloblastomas and in normal mucosal epithelium on each. Attained results as follows ; 1. EGF, EGFR, aFGF, bFGF, FGFR, and VEGF showed more intense stainability on experimental group compare t，。 that on the control group. 2. EGF, EGFR, aFGF, bFGF, FGFR, and VEGF showed more intense stainability in epithelial component and more intensely stained on the peripheral ce11s of the ameloblastomas. 3. EGF, EGFR, aFGF, bFGF, FGFR, and VEGF showed positive stainability on the stromal tissues but its level is lower compare to that on the epithelial components. Those results suggested that those growth factors take a role in development and progression on the amelob비las와tomas
