16HBE cells exposure in vitro to silica (50 µg/ml), bFGF (20 ng/ml), or silica + bFGF for 24 hr: Effects on collagen synthesis. All cultures were added with 3H-methionine (25 µCi/ml). Values (mean 6 SD) were derived from three separate experiments, each in quadruplicate. Data were analyzed by ANOVA. Differences versus control: *F-test significant at 99%; **F-test significant at 95%.
