Figure 8: Ultrastructure demonstrating axon regrowth and remyelination. Varying levels of regeneration and myelinogenesis were observed at three time points. At 9 weeks, obvious axon necrosis or myelin sheath cell apoptosis was observed (white arrow). Marked remyelination (green arrow), vast axon regrowth (red arrow), and alignment of regenerated axons were observed at 17 weeks, in comparison with those at 9 and 13 weeks after transfer. Data are expressed as the mean ± SEM (n = 10; one-way analysis of variance followed by the least significant difference post hoc test). *P < 0.05, **P < 0.01, ***P < 0.001. The G-ratio declined over time.
