Fig. 6.
The growth of axons derived from graft along the corpus callosum. There were more AP-positive fibers along the corpus callosum at the ipsilateral side near the graft and there was no significant difference between 2 and 5 weeks post-transplantation. The number of AP-positive fibers decreased with distance. At the midline and contralateral of the corpus callosum, there was a significant decrease in AP-positive fibers in animals at both 2 and 5 weeks, *P < 0.001, ipsilateral vs midline, and ipsilateral vs contralateral at 2 and 5 weeks. There was no difference in AP-positive fibers comparing midline with contralateral at both 2 and 5 weeks (P > 0.05).
