Figure Lengend Snippet: Electrical stimulation promoted the repolarization of M1 macrophages into M2 macrophages. (a) Cell viability after ES was assessed using the CCK8 assay. (b) Flow cytometry analysis of CD86 + M1 and CD206 + M2 macrophages in control, LPS-treated, and ES-treated (0.1 V/cm, 0.25 V/cm) RAW264.7 cells. MFI, mean fluorescence intensity. (c) Reactive oxygen species (ROS) detection in control, LPS-treated, and ES-treated (0.1 V/cm, 0.25 V/cm) RAW264.7 cells. (d) Western blot analysis of M1 markers (CD86, iNOS, TLR4) and M2 markers (CD206, CD163, CD209) in control, LPS-stimulated, and LPS + ES-treated (0.25 V/cm) RAW264.7 cells. (e) Quantitative analyses of macrophage phenotype marker expression. (f) ELISA analyses of TNF-α, IL-1β, IL-6, and IL-10 secretion in macrophage culture supernatants. Data are shown as the mean ± SEM and were analyzed using one-way ANOVA followed by Tukey’s post-hoc test . ## p < 0.01 and ### p < 0.001 vs . the control group. * p < 0.05, ** p < 0.01, and *** p < 0.001 vs . the LPS group ( n = 3 per group).
