| Outline of Final Research Achievements |
We created sciatic nerve and central nerve injury models in 4-week-old rats and examined regeneration under the influence of a magnetic field using a Helmholtz coil.It was suggested that macrophages migrate to the injured area and rapidly remove debris caused by the injury, thereby suppressing fibroblasts. Microarray analysis revealed increased expression of Actn2 and 3, and immunohistochemistry also revealed F-actin in the growth cones of regenerating axons, suggesting that actin may contribute to axon elongation.
