Figure 6From: Cigarette smoke and lipopolysaccharide induce a proliferative airway smooth muscle phenotype CSE and LPS induce BTSM hypocontractility. Methacholine (A)- and KCl (B)-induced contractions of BTSM strips cultured for 8 days with or without LPS (1 μg/ml) or exposed to 15% CSE for 1 h daily during 8 days. Data represent means ± S.E.M. of 4-6 experiments, each performed in duplicate. *P < 0.05 vs control.Back to article page
