Effects of QCN on muscle atrophy of the BPA rats at week 8 post-avulsion. A Representative images of biceps muscles in both of the ipsilateral and contralateral sides. B The rate of wet weight of the biceps muscles. C Histological images of longitudinal bicep sections with H & E staining. D The percentage of fibroblast nuclei number in the ipsilateral to contralateral biceps. E Representative Z-Stack images of biceps muscles sections stained with FITC-conjugated α-BTX. F Average area of MEPs in each group. Data are expressed as the mean ± SEM (n = 6). ^### p < 0.001 vs the sham group; **p < 0.01 and ***p < 0.001 vs the vehicle group.
