| Outline of Final Research Achievements |
We studied nerve regeneration using Thy1 YFP-16 mice. There was correlation between fluorescence intensity and histological axon regeneration in Thy1 YFP-16 mice, with the number of regenerated axons showing the strongest correlation. In brief electrical stimulation, the speed of axon growth in early stage was faster in the 60-minute stimulation group as compared with other groups, suggesting that it may primarily reduce the period where regenerated axon travels beyond the crush site. Moreover, regeneration promoting effect was observed in motor nerves as well as sensory nerves, thus application to various scenes can be expected in the future.
