a Schematic representation of injured spinal cord. Transverse sections were prepared from 6 mm rostral b, or adjacent to the lesion site (F). b The number of MPO-positive neutrophils was decreased in the injured spinal cord of CI-994-treated mice at 1 day and 3 days after SCI. dpi: days post injury. Scale bar: 200 μm. c Dot plots of isolated immune cells in the spinal cord, gated for live cell analysis. d Representative cytometry data for neutrophils (Ly6C+/Ly6G+ cells) in the injured spinal cord 3 days after SCI. e Quantitative data for accumulated neutrophils in the injured spinal cord up to 7 days after SCI. f Numbers of CD68 (ED-1)-positive activated microglia/macrophages were not altered in the injured spinal cord of CI-994-treated mice. Scale bar: 200 μm in low-magnification images, 100 μm in high magnification images. g Representative cytometry data for macrophages (Ly6C+/CD11b+ cells) in the injured spinal cord at the indicated days after SCI. hQuantitative data for accumulated macrophages in the injured spinal cord up to 7 days after SCI. Results are presented as the mean ± SE (n = 3–6). *p< 0.05, Two-way repeated-measures ANOVA. SCI: spinal cord injury; MPO: myeloperoxidase
