Fig. 5From: Ginsenoside Rg3 inhibits pulmonary fibrosis by preventing HIF-1α nuclear localisationHIF-1α reverses the inhibitory effect of Rg3 on fibrosis. We overexpress HIF-1α in mice with bleomycin-induced pulmonary fibrosis after treatment with Rg3, and then evaluate the degree of pulmonary fibrosis. a HE staining was performed to detect the morphology of lung tissue (× 100 magnification). b Masson staining was conducted to detect the proportion of fibroblasts (× 100 magnification). c Immunohistochemistry was applied to observe the expression of TGFΒ1 and EMT markers (× 100 magnification)Back to article page
