Trichrome staining and Ashcroft scoring reveal the pattern of fibrotic burden during the bleomycin-induced murine model of pulmonary fibrosis. Mice were treated with bleomycin (1 U/kg, IT) or normal saline control followed by lung tissue collection. Masson’s trichrome staining (A) and Ashcroft scoring (B) was performed at indicated time points. Scale bar = 4 mm. Data are represented as mean ± SD
