Fig. 9From: Bone marrow mesenchymal stromal cells attenuate silica-induced pulmonary fibrosis potentially by attenuating Wnt/β-catenin signaling in ratsImmunohistochemical expression and localization of P-GSK-3β (a) and β-catenin (b) in lung tissues of each group, magnification × 100, × 200, and × 400. a P-GSK-3β is deposited in the cytoplasm of the silica model group and transplantation group. b β-catenin is deposited in the cytoplasm of the silica model group and transplantation group. Aggregation staining of β-catenin in nucleus was indicated by the arrowBack to article page
