Figure 3From: Macrophage metalloelastase (MMP-12) deficiency does not alter bleomycin-induced pulmonary fibrosis in miceLevels of TGF-β-1 (A), and TIMP-1 (B) in BAL supernatant fluids, recovered from WT (blank bars) and MMP-12 -/- mice (solid bars), at day14 after intranasal administration of bleomycin (BLM) or saline vehicle (Control). For TGF-β-1 and TIMP-1, results are represented as the mean (pg/ml) ± SEM. ** : P < 0.01 compared to corresponding control. n = 5–8.Back to article page
