Data are derived from dystrophic (mdx) mouse quadriceps muscles before and after injury

TSA total stained area, TSP total stained perimeter, TA total area, TP total perimeter, DI dispersion index

DI was calculated as (TSA/TA) * 100 and describes density of acetylcholine receptors. All data are presented as mean ±SD, p < 0.05. *, indicates statistical significance from non-injured
