Figure 6From: Differential effects of cigarette smoke on oxidative stress and proinflammatory cytokine release in primary human airway epithelial cells and in a variety of transformed alveolar epithelial cellsCigarette smoke extract caused necrosis with no or little evidence of apoptosis in murine type II epithelial cells (MLE-15). Murine type II epithelial cells (MLE-15) were treated with media alone (control) and various concentrations of CSE; a) control, b) CSE (1.0%), c) CSE (2.5%), d) CSE (5.0%), e) CSE (7.5%), f) CSE (10%) for 24 hr. Results are mean of 3 experiments ± SEM. §p < 0.001 compared with control group L = Live; A = Apoptosis; N = Necrosis.Back to article page
