Haematoxylin and eosin staining for lungs treated with control media (a) and iPSC conditioned media (b). Administration of iPSC-cm to bleomycin-injured rat lungs showed significant attenuation of fibrosis as assessed by semi-quantitative analysis using the Ashcroft score (control media 3.93 ± 0.30 vs iPSC-cm treated 2.4 ± 0.34), healthy controls: (1.74 ± 0.42) (c). In accordance, marked reduction in the soluble collagen content was detected in the lungs of iPSC-cm-treated animals compared with bleomycin animals (57.74 ± 9.3 μg/mg vs. 202 ± 29.57 μg/mg). Collagen content of healthy lung was 10.04 ± 1.49 μg/mg (d)
