MPLA attenuated irradiation-induced inflammation and structural damage in mice lung tissue. A–D, Representative images showing the HE staining, Masson trichrome staining and TUNEL assay results of lung tissue sections at 1-week, 4-week, 8-week and 16-week post-irradiation. E, Ashcroft scoring of HE staining of lung tissues (The score of NC group and MPLA group was 0 score, one image per mice). F, Ashcroft scoring of Masson trichrome staining of lung tissues (one image per mice). G, Representative images of the TUNEL assay of lung tissues (one image per mice). H, The lung coefficient of mice in each group. Data are shown as the means ± SEM, n = 3 mice per group. *P < 0.05, **P < 0.01, *** P < 0.001,****P < 0.0001
