Total and differential cell counts of BAL fluid from MMP-12 -/- and WT mice 14 days after intranasal administration of bleomycin (BLM) or saline vehicle (Control). Results are presented as the mean (.10³cells) ± SEM. n: number of mice. a: P < 0.05, b: P < 0.01, c: P < 0.001 compared with control mice exposed to saline solution only.
