Neutrophil percent and concentration in the BAL of wild-type, TIMP-1^−/−, and TIMP-2^−/− mice at Day 7 after bleomycin administration. Mean values (± SE) for neutrophil percent (A) and neutrophil concentration (B) in the BAL of wild-type (white column), TIMP-1^−/− (black column), and TIMP-2^−/− (striped column) mice at Day 7 after a single intratracheal dose of bleomycin. Six mice were analyzed for each genotype. *P < 0.05, comparison of TIMP-1^+/+ with TIMP-1^−/−; **P < 0.001 comparison of TIMP-1^−/− with TIMP-2^−/−.
