Recruitment of M2 macrophages at the lesion site of injured rat spinal cords after DcR3.Fc treatment. Expressions of Arg I and CD206 at the lesion sites of DcR3.Fc-treated and control SCI rats. a, b Detection of the Arg I expressions at the lesion sites of the two groups by Western blot analysis (a **p < 0.01, N = 3) and qPCR (b **p < 0.01, N = 5). c, d Detection of Arg I/OX42-positive cells (c) and CD206/OX42-positive cells (d) at the lesion sites of the two groups of rats by immunofluorescence staining (left, scale bar: 100 μm), and quantification as the percentage of Arg I/OX42-positive area (c right, **p < 0.01, N = 3) and CD206/OX42-positive area in the lesion area (d right, *p < 0.05, N = 3). The results are presented as means ± SEM
