Figure 7From: The effect of cathepsin K deficiency on airway development and TGF-β1 degradationEffects of CatK expression on the migration and proliferation of MLFs. Quantitative analysis of crystal violet assay (CVA) (A) and MTT assay (B) after MLFs were incubated with TGF-β1 (5 ng/ml) for 0-72 h. (C) phase images of wound healing and wound closure rates (D) show that CatK-deficient MLFs facilitate wound closure. * p < 0.05, ** p < 0.01 compared with same time point.Back to article page
