Fig 7. TMPRSS4 deficiency attenuates bleomycin-induced lung damage in mice.

Wild type (WT), TMPRSS4 deficient (KO) and haplodeficient (HT) mice were instilled intratracheally with bleomycin (7 U/Kg) or saline solution and studied at 28 days. Panel A: control mice instilled with saline solution. Panel B: mice with bleomycin-induced pulmonary fibrosis. Histopathologic analysis was performed using hematoxylin and Masson trichrome staining.
