The effect of YKL-40 treatment on α-SMA protein expression in lung fibroblast cells. Lung fibroblast cells were treated with 0, 10 or 100 ng/ml YKL-40 for 48 h. Measurements of α-SMA expression upon stimulation by YKL-40 as determined by immunofluorescence staining (a), and Western blot analysis (b); Analysis by densitometry of immunodetection of α-SMA (c). Results were expressed as mean ± SEM of three independent experiments
