BLM-induced pulmonary fibrosis formation was suppressed in TKKO mice. a Hematoxylin-eosin staining of the lung in WT mice and TKKO mice on day 21 after BLM treatment. The red arrow indicates the fibrotic area. Bar = 200 μm. b The fibrotic area in the lung on day 21. Data are expressed as the mean ± SD (n = 8-12 mice per group). **p < 0.01 versus WT mice. c Ashcroft score WT mice and TKKO mice on day 21. Data are expressed as the mean ± SD (n = 14-17 mice per group). ****p < 0.0001 versus WT mice [11]
