Compared with mice from the PBS‐BLM group, infusion of IL10‐M on days 1 and 7 reduced lung injury and pulmonary fibrosis more remarkably, as shown by the micro‐CT images and corresponding scores of the lungs (Figure 2b, c), H&E (Figure 2d, e) and Masson's trichrome staining (Figure 2f). The gene discussed is IL10; the disease is pulmonary fibrosis.
