Regenerating and necrotic myofibres in NT-MAG-Exo myo III- and non-magnetic NT-Exo myo III-injected muscle tissue were stained with embryonic myosin (eMHC, yellow) and laminin (magenta), or with goat anti-mouse IgG (grey). Scale bars, 50 m. Immunoreactive fibres were quantified per mm 2 using ImageJ software; n = 5 mice per group. Data are presented as mean s.d. Statistical analyses were performed using Kruskal Wallis with Dunn’s multiple-comparison test.
