Figure 1

Regeneration-related activity in LVP, MAS and TA muscle. (a–f) Immunofluorescence staining of laminin (green), Pax7 (red) and DAPI (blue) in muscle cryosections from LVP, MAS and TA muscle, at either three-week age or ten-week age. White arrows indicate Pax7+ve nuclei. (g,h) Quantification of the percentage of Pax7+ve nuclei in total nuclei. (i–n) Immunofluorescence staining of Ki67 (red) and DAPI (blue) in muscle cryosections from LVP, MAS and TA, at either three-week age or ten-week age. (o,p) Quantification of the percentage of Ki67+ve nuclei in total nuclei. (q–v) Immunofluorescence staining of laminin (green) and DAPI (blue) in muscle cryosections from LVP, MAS and TA, at either three-week age or ten-week age. Yellow arrows indicate centrally-nucleated myofibers. (w,x) Quantification of the percentage of centrally-nucleated myofiber in total myofibers. For each group, N = 6. *p < 0.05; ***p < 0.001.
