Pax7⁺ cells are increased 3 and 10 days after repeated injury: A Schematic diagram of the experimental approach. B Representative images of proliferating Pax7⁺/ki-67⁺ SCs in muscle sections, 3 days after single or repeated injury. C and D Quantification of the number of Pax7⁺ cells per field of view (FOV) and of the percentage of Pax7⁺/ki-67⁺ SCs in muscle sections. n = 6 independent samples. E Representative images of Pax7⁺/ki-67⁺ SCs in muscle sections, 10 days after single or repeated injury. F and G Quantification of the percentage of Pax7⁺/ki-67⁺ SCs and the number of Pax7⁺ cells per muscle fiber. n = 6 independent samples. H Representative images of Pax7⁺ cells in muscle sections, 30 days after single or repeated injury. I Quantification of the number of Pax7⁺ cells per muscle fiber. n = 5 independent samples. Data are shown as mean ± S.E.M. *p < 0.05; **p < 0.01; ***p < 0.001
