a Stimulated proliferation of keratinocytes by recombinant KGF is not concentration dependent. Data were recorded over 96 h, error bars represent ±1 standard deviation; statistically significant (P ≤ 0.05) stimulation was observed at 72 and 96 h, as marked by asterisks. Measurements were performed in triplicate, and experiments were repeated at least three times. b KGF-induced (0.2 μg/ml recombinant KGF) stimulated proliferation of irradiated keratinocytes was abrogated by the addition of anti-KGF antibody to the medium. Data shown were recorded after 96 h of incubation. Error bars represent ±1 standard deviation; statistically significant (P ≤ 0.05) inhibition of proliferation is marked by asterisks. Measurements were performed in triplicate, and experiments were repeated at least three times
