In vivo differentiation of human cremaster muscle-derived myogenic precursor cells. (A) Outline of the experimental design. (B–H) Immunofluorescence of histological sections from the control TA group (B,D,G) and the experimental TA group (C,F,H), respectively. (B,C) Histological analysis of the grafted cell survival through human LAMIN A/C detection by immunofluorescence (green). (D–F) Detection of human LAMIN A/C (green) and PAX7 (red) expressing satellite cells localized in their niche by immunofluorescence (arrows, E). (G,H) Detection of human LAMIN A/C (green) and human DYSTROPHIN (red) positive fibres. Nuclei were counterstained with Hoechst 33258 (blue). Scale bars, 100 μm.
