Fig 2. Inflammation assessment using the LSS model.

(A) Representative immunofluorescence images of CD68⁺ macrophages in the spinal cord. Yellow scale bars = 1 mm and white scale bars = 100 μm. (B, C) Quantitative analyses of the (B) intensity and (C) number of CD68⁺ macrophages in the sham and LSS groups (n = 4 per group). Data are expressed as the means ± SEM. *P < 0.05, **P < 0.01, and ***P < 0.001 compared with the sham group analyzed by a one-way ANOVA with Tukey’s post-hoc test.
