Therapeutic effects of hUC-MSCs combined with P₃₀ in BLM-induced pulmonary fibrosis in mice. A The Kaplan–Meier survival curves of different groups (n = 10). B The total soluble collagen content in the right lungs of different groups of mice (μg/right lung) (n = 10). C, E Representative pictures of HE and Masson staining of lung sections of different groups of pulmonary fibrosis mice. Scale bars: 200 μm. D, F The Ashcroft score of HE and Masson staining of different groups (n = 4). G, H, I The mRNA levels of main pulmonary fibrosis markers (Col1a1, Col1a2, and α-SMA) in different groups of pulmonary fibrosis mice. Values are means ± SEM (n = 3).*p < 0.05; **p < 0.01;***p < 0.01
