Mice were delivered the indicated cSCK intratracheally and evaluated by lung bronchoalveolar lavage (BAL) after 24 h. (A) Total cell number and (B) percentage of individual cell types (Mac, alveolar macrophage; Lymph, lymphocyte; Neutro, neutrophil) recovered in BAL fluid. (A, B; 9 independent experiments, n=4–6 mice/treatment) (C) Inflammatory mediators elevated in cell-free BAL fluid measured by Bio-Plex multi-analyte assay (5 independent studies, n=4–7 mice/treatment). All data are the mean ± S.D. A significant difference compared to non-PEG cSCK (*) and PBS (†) (P < 0.05), is indicated.
