[Retracted] PM2.5 Exposure Induces Lung Injury and Fibrosis by Regulating Ferroptosis via TGF-β Signaling

Figure 1

PM2.5 promotes lung fibrosis in mice. (a–c) The mice were treated with PM2.5 for 15 days or 30 days. (a) The lung injury was measured by H&E staining. (b) The lung fibrosis was detected by Masson staining. (c) The levels of α-SMA, collagen I, and collagen III were analyzed by IHC staining.
