FIGURE 3.

Transmission electron micrographs showing the ultrastructure of the spinal cord at 28 d post‐injury (n = 6 mice per group). (a) WT mice. (b) ApoE ^–/– mice. (c) Quantification of the ratio of demyelinated axons to total axons in the experiments. Scale bar = 1 μm. White arrows: demyelinated axons; black arrows: normal axons. White asterisk: neuron nucleus; black asterisks: oligodendrocyte nuclei. All data are mean ± SD.

Abbreviations: ApoE, apolipoprotein E; EA, electroacupuncture; SCI, spinal cord injury; WT, wild type. ^** p < .01, ^*** p < .001 vs. WT EA+COG112 group. ^## p < .01, ^### p < .001 vs. ApoE ^–/– EA+COG112 group
