a No stimulated proliferation by recombinant KGF added to tumour cell cultures for 72 h. Open symbols represent cells plated in KGF-free medium; closed symbols represent cells plated in medium containing 0.2 μg/ml recombinant KGF. Data were recorded over 72 h, error bars represent ±1 standard deviation. Measurements were performed in triplicate and experiments were repeated at least three times. b No effect of recombinant KGF added to tumour cell cultures for 96 h. Closed bars represent cells plated in KGF-free medium; horizontal stripes represent cells plated in medium containing 0.2 μg/ml recombinant KGF. Data were recorded over 96 h, error bars represent ±1 standard deviation. Measurements were performed in triplicate, and experiments were repeated at least three times
