Depleting microglia reduced inflammatory cells at the lesion site. (a) Representative images showing iNOS⁺ cells and Arg1⁺ cells at the lesion site without microglial depletion. (b) Representative images showing iNOS⁺ cells and Arg1⁺ cells after microglia depletion (a-b Scale bars = 50 μm). (c) Densities of iNOS⁺ cells and Arg1⁺ cells in the periphery area of lesion site with microglia depletion or not (n = 4, *p <0.05, **p <0.01)
