Figure Lengend Snippet: Effect of DSF on S100A4 + macrophages in the lung tissues of BLM-induced lung fibrosis in mice. ( A – C ) Representative immunostaining images for S100A4 in the lung tissue of untreated ( A ), DSF non-treated ( B ) and DSF-treated ( C ) mice on day 28. Higher-magnification images in the lower left correspond to the areas indicated by dashed squares. Scale bars = 200 μm. ( D ) Representative bright-field and double-fluorescence staining images in the lung tissues of BLM-treated mice on day 28. DAPI (4′,6-diamidino-2-phenylindole) is shown in blue, CD68 in green, and S100A4 in red. The bright-field image was generated from fluorescent images using inForm software. Higher-magnification images correspond to the area indicated with dashed squares. Arrowheads indicate S100A4 + CD68 + macrophages. Scale bars = 25 μm. ( E ) Number of S100A4 + cells in the lung tissue on day 28 counted in immunostaining images ( A – C ). n = 5 per group. * P < 0.05, ** P < 0.01 (Tukey’s test). ns, not significant.
Article Snippet: We used the following primary antibodies: anti-human α-smooth muscle actin (α-SMA) mouse monoclonal antibody (1:250 dilution, Dako, Glostrup, Denmark), anti-human CD34 mouse monoclonal antibody (1:100 dilution, Nichirei Bioscience, Tokyo, Japan), anti-human CD68 mouse monoclonal antibody (1:200 dilution, Dako, Glostrup, Denmark), anti-human/mouse S100A4 rabbit monoclonal antibody (1:100 dilution, Abcam, Cambridge, UK), and anti-human FROUNT goat polyclonal antibody (1:150 dilution, Everest biotech, Oxfordshire, UK), followed by peroxidase-labelled secondary antibodies, and incubated with Opal fluorophore Opal 690, Opal 540, Opal 570, Opal 620, Opal 520, respectively.
