From: Bronchiolar chemokine expression is different after single versus repeated cigarette smoke exposure
Repeated CS exposure induces inflammatory cell recruitment. Mice were repeatedly exposed to CS for up to 10 days and the cell content in the BAL fluid was identified as described in Materials and Methods. Data represent the average number of total cells (A), macrophages (B), neutrophils (C), and lymphocytes (D) per ml BAL fluid ± SEM from eight mice. Statistical significance: * = p < 0.05; ** = p < 0.01; *** = p < 0.001.
