A Schematic showing experimental design. B Survival rate of the model mice. C Morphology and histology of the lung tissue with different stains (HE, Sirius red and Masson); scale bar = 200 μm. D Ashcroft score of histological images (scored by three pathologists blind to treatment). E HYP content of the lung tissue. Value: Mean ± SEM; *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001 as indicated by Student’s t test; n = 5. ADSC adipose-derived stem cells, BLM bleomycin, N.S. normal saline, CTRL control, HE hematoxylin and eosin, HYP hydroxyproline.
