Figure 5
Immunohistochemical staining of TGF-β1 in the lung tissue of mice in each group (400-fold, scale bar = 50 μm). NC, normal control group; BLM, bleomycin-induced systemic sclerosis model group; PESV-L, low-dose PESV intervention group; PESV-M, medium-dose PESV intervention group; PESV-H, high-dose PESV intervention group; DXM, dexamethasone intervention group.
