ATL‐III regulated the M1/M2 polarization of microglia/macrophages in rats after SCI. (A–H) Typical immunohistofluorescence pictures of CD68 (green), CCR7 (red in A–C), Arg‐1 (red in E–G), and nuclei (blue) in the spinal cords of sham, control, and ATL‐III rats. (D,H) The numbers of CD68⁺CCR7⁺ (M1 cells) and CD68⁺Arg‐1⁺ (M2 cells) cells. (I–K, M–O) Typical flow cytometry images of myeloid tissues from sham, control, and ATL‐III rats. (L,P) Proportions of CD68⁺CCR7⁺ and CD68⁺CD206⁺ cells. The data are presented as the mean ± SD (n = 6). *p < 0.05, **p < 0.01 compared with the control rats
