Objective To investigate the effect of HGF on proliferation and migration in cultured human RPE cells. Methods Human RPE cells cultured in serum-free medium were treated with HGF(1,2,10,50,100 mu;g/L), and MT T assay was used to detect the growth of the cells; an in vitro wound healing model was used to count the number of cells that had entered the denudate area in RPE mig ration treated with HGF (1,2,10,50,100 mu;g/L) after 20 h. Results HGF(10,50,100 mu;g/L) increased proliferation rates of cultur ed human RPE (18.2 % to 34.8 %), and at a concentration of 50 mu;g/L on day 3 HGF induced the maximal increase of proliferation (P lt;0.01); HGF showed effects on migration of 9.3 %, 113.0 %, 91.7 % and 50.3 % at the concentrations of 2,10,50, 100 mu;g/L, respectively. HGF stimulated t he best migratory response in RPE cells at a concentration of 10 mu;g/L (113 %). Conclusion HGF can induce the proliferation and obvious migration of RPE cells, consequently HGF was a mitogen and potent migratory factor for human cultured RPE cells.
