| Outline of Final Research Achievements |
In the histologic evaluation by the toluidine blue and anti S-100 antibody staining, there were more nerve regeneration in ADRC tlansplantation group. However, by the functional evaluation of the exercise-induced EMG and walk analysis, the meaningful difference between each group were not recognized. The effect of the amyotrophy prevention was expected with porting ADRC to a skeletal muscle as well as nerve defect.
Because of the ADRC signal disappearance in in vivo imaging and of few human derived cells in immunostaining, it was difficult to consider that ADRC differentiated to a nerve and blood vessel directly as the mechanism of the nerve regeneration by the ADRC transplantation, and was supposed that some kind of paracrine effects worked by ADRC porting.
