Total white blood cell (WBC) and differential cell count in bronchoalveolar lavage fluid (BALF) in the lipopolysaccharide (LPS) (A) and cecal ligation and puncture (CLP) (B) groups, as well as BALF protein levels (C). Values expressed as mean ± standard deviation of four to six animals per group. *Significantly different from corresponding control group (C or sham) (P <0.05). #ARDS-BMDMC vs. ARDS-SAL (P <0.05).
