Idiopathic pulmonary fibrosis (IPF) is a condition in which the lungs become scarred and breathing becomes increasingly difficult.
BLM-induced IPF model
Validation data
The results revealed evident interstitial pneumonia and fibrotic features in the bleomycin-induced mouse lungs.
Drug efficacy
The immunohistochemistry results indicate that following PFD treatment, there is a noticeable reduction in the expression of fibroblast marker α-SMA (brown) . HE staining (whole slide scan) and Masson's staining demonstrate that PFD can significantly alleviate the overall interstitial pneumonia induced by BLM (characterized by neutrophil infiltration foci and pulmonary parenchymal changes) as well as fibrosis (Masson's blue).
