Fig. 7From: Bone marrow mesenchymal stromal cells attenuate silica-induced pulmonary fibrosis potentially by attenuating Wnt/β-catenin signaling in ratsa Severity of pulmonary fibrosis evaluated by modified Ashcroft score (on the 56th day after exposure to silica suspension). b Hydroxyproline content in lung tissues of each group (on the 56th day after exposure to silica suspension). Data are presented as mean ± SD. *o < 0.05 compared with the control group, #p < 0.05 compared with the silica model groupBack to article page
