Satellite cells retain S6 phosphorylation 50 days after cardiotoxin injury. A Representative images of Pax7⁺/pS6⁺ SCs isolated from uninjured muscle or 50 DPI. B Quantification of the percentage of pS6⁺ SCs. n = 6 independent samples. C Representative Pax7⁺/pS6⁺ and Pax7⁺/pS6⁻ SCs in a TA muscle section. Arrows indicate a Pax7⁺/pS6⁺ SC (upper arrow) and a Pax7⁺/pS6⁻ SC (lower arrow). D Quantification of the percentage of pS6⁺ SCs in muscle sections 50 DPI, or in uninjured control muscle. n = 6 independent samples. E Representative images of Pax7^hi and Pax7^lo cells isolated from muscle 50 DPI or from uninjured control muscle. F Quantification of the percentage of Pax7^hi and Pax7^lo SCs isolated from muscle 50 DPI or from uninjured control muscle. n = 5 independent samples. Data are shown as mean ± S.E.M. *p < 0.05
