Figure 1

Time course of macrophage/microglia polarization. iNOS+ CD11b+ cells refer to a M1 phenotype, Arg1+CD11b+ cells refer to a M2 phenotype. Positive cells in the merged panels exhibit a yellow signal. The corner pictures are enlarged images of the small frame in each panel. Bar = 200 μm. iNOS, inducible nitric oxide synthase; Arg1, arginase 1. 1 dpi, 3 dpi, 7 dpi, and 14 dpi refer to 1, 3, 7, and 14 days post-injury, respectively.
