Gefitinib Inhibits Bleomycin-Induced Pulmonary Fibrosis via Alleviating the Oxidative Damage in Mice

Figure 2

α-SMA and HMGB1 were highly expressed in the lung tissues affected by pulmonary fibrosis. Lung sections from mice were collected on day 14 after intratracheal bleomycin (BLM) or PBS administration and were stained with H&E, Masson’s trichrome, and immunohistochemical stains (magnification 200x).
