Outline of Final Research Achievements |
The expression levels of mRNAs encoding M-cadherin and MyoD in the TA muscle of the DNV group were significantly higher (p<0.01) than in the control throughout the study period. These mRNA levels in the ANS group were significantly higher (p<0.01) at ≦ 1week than in the controls, but fell to control levels at ≧ 3weeks. In the ANS group, recovery of muscle area and NMJ structure occurred by 3 weeks. These data suggested that NMJ formation following reinnervation might prompt recovery of M-cadherin and MyoD mRNA expression to the quiescent level of SCs.
