Figure 6From: Nitric oxide exerts protective effects against bleomycin-induced pulmonary fibrosis in miceThe n/i/eNOS−/−mice exhibited an increased production of CTGF and collagen I. (A) Immunostaining for CTGF and collagen I in the lungs of the WT and n/i/eNOS−/− mice. Scale bar = 100 μm. (B) CTGF mRNA expression (n = 5). (C) Collagen I mRNA expression (n = 5).Back to article page
