Figure Lengend Snippet: Effects of mAF treatment on hepatic macrophages in CGI-58 LivKO mice. (A) Representative IHC images and quantification of the (B) M1 macrophage marker CD68, (C) M2 macrophage marker CD206, and (D) ratio of CD68 to CD206 in the liver of mice. Data are presented as mean ± SD. n = 8 for treatment group, and n = 3 for ALB- group. *P < 0.05, **P < 0.01 by Student’s t-test. Scale bars: 50 μm.

Article Snippet: The expression of CD68 and CD206 in the liver was evaluated by immunohistochemical staining using primary antibodies against mouse CD68 (1:4,000 dilution, Abcam, Waltham, MA) or mouse CD206 (1:1,600 dilution, Cell Signaling Technology ® , Danvers, MA).

Techniques: Marker

Immunofluorescence staining of (A) M2 macrophages (red: CD68; green: CD206; blue: nuclei) and (B) M1 macrophages (red: CD68; green: CD80; blue: nuclei) one week after the implantation of various membranes into critical-sized calvarial bone defects in mice. (C) Quantification of the number and ratio of M2 macrophages to M1 macrophages. Data were shown as mean ± SDs. ns, no significance, ∗∗∗ P < 0.001, ∗∗ P < 0.01, ∗ P < 0.05.
