Light microscopy of cross-sections from the site of injury. Transverse sections (4 μm) were taken from the center of the lesion site of contused spinal cords treated with anti-MBP T cells or PBS and stained with H&E (E–H) or luxol (A–D). A, C,E, and G show sections from control rats.B, D, F, andH show sections from rats treated with anti-MBP T cells.Arrowheads and arrows point to myelinated axons and neuronal cell bodies, respectively. C andD are enlargements of the boxed areas seen inA and B; G andH are enlargements of E andF.
