Infiltration of macrophages/microglia cells and SCs in lesion sites 2 weeks after SCI. (A–D) were CD68⁺ cells (green) and ARG1⁺ cells (red) of different groups. (E–H) were SCs (S100⁺, red) of different groups. Cell nuclei were stained by DAPI in (A–H). These images were from the sites labeled with "*" in Fig. S3. Quantitative analyses number of ARG1⁺ (I), percent of ARG1⁺/CD68⁺ cells and number of S100⁺ cells (K) in the lesion sites were presented. *P < 0.05, **P < 0.01, ***P < 0.001. (n = 6).
