Fig. 2. Histopathological evaluation of the spinal cord in normal control and SCI-induced rats on D7PI. (A~C) Cell infiltration in SCI rats (B and C) normal controls (A). ED1-positive macrophages in the core lesions of the SCI+vehicle-treated group (E) and SCI+alendronate 1 mg/kg-treated group (F). Under alendronate treatment, the size of the ED1-positive area was reduced (G). Scale bars=50 μm. *p<0.05; ***p<0.001 vs. normal control. #p<0.05 vs. SCI+vehicle-treated group.
