Quantification of muscle fiber diameter in control versus MFN2 mutant mice (see Table 2).

<p>Bar histograms quantifying the diameters of fast muscle fibers in the peroneus (Pero), lateral gastrocnemius (Gastro), tibialis anterior (Tib) muscles and the number of fast and slow/mixed fibers in the soleus (Sol) muscle of control (open bars) and MFN2 mutant mice (dark bars) showing mean ± SEM. (* denotes statistical difference, p< 0.03 while ** denotes p< 0.015, n = 4, using Wilcoxon-Mann-Whitney test).
