TUDCA treatment promotes microglia polarization toward the M2 phenotype. A, C Immunofluorescent staining of Iba-1(red) /CD163(green) or CD68(red)/CD163(green) in the lesion site of the spinal cord 14 days after SCI. B, D Quantification the number of Iba-1⁺/CD163⁺ or CD68⁺/CD163⁻ cells in spinal cord. All experiments were performed in triplicated and data were presented as means ± SD, n=3 per group. *P < 0.05, **P < 0.01
