| Outline of Final Research Achievements |
To know the cellular mechanism of exercise-dependent facilitating recovery of atrophied muscle, I examined the effects of exercise on the number of nuclei of individual myofibers in atrophied and normal muscles. Results, the exercise promoted recovery of atrophied myofiber CSA, and the number of newly generated myonuclei increses. And proliferation, differentiation and fusion of myogenic satellite cells were observed, suggesting that the activation of myogenic satellite cells induced by exercise effectively facilitate the recovery of size of myofibers from the muscle atrophy.
