TEM of regenerating nerve and walking track analysis.

<p>(A and B) At 8 and 12 weeks after injury, ultrathin cross-sections of regenerating sciatic nerve were assessed with TEM. Scale bar = 2 µm. (C) Statistical analysis of myelinated axon diameters. (D) Statistical analysis of myelin sheath thicknesses. (E) Statistical analysis of the G-ratio. (F) Walking tracks were analyzed to assess motor function at 2, 4, 6, 8, 10, and 12 weeks after surgery. n = 5, *p<0.05, **p<0.01.
