In addition, changes in biochemical (HP) and histological markers (Ashcroft score, PSR, Col1a1, Col3, α‐SMA, Gal‐3) were similar across all lung lobules (left lung lobule, right inferior lobule, right superior lobule) in BLEO‐IPF mice (Figure S4), indicating that changes in left lung lobule markers of fibrosis and inflammation were representative for whole‐lung changes in the model. This evidence concerns the gene COL1A1 and idiopathic pulmonary fibrosis.
