Functional analysis of human dystrophin derived from human artificial chromosome in skeletal muscles. (A) H&E staining of skeletal muscles of WT, DMD-null, and DYS-HAC1; DMD-null mice at more than 8 weeks of age. Scale bar is 50 μm. (B) CK activity in WT (n = 19), DMD-null (n = 14), and DYS-HAC1; DMD-null mice (n = 9) at more than 8 weeks of age. (C) Voluntary wheel running in WT (n = 13), DMD-null (n = 8), and DYS-HAC1; DMD-null mice (n = 9) at more than 8 weeks of age. Tukey’s multiple comparisons test was performed. ***P < 0.001. NS nonsignificant.
