Fig. 4. Fiber diameter (A) and area (B) distributions of restored dystrophin-expressing myofibers generated by the various myogenic populations. A larger percentage of small, newly formed fibers is seen with the LP population, and the overall range of distribution of the EP-generated fibers suggests that they may be more likely to fuse with larger host myofibers. Mdx myofiber analysis of non-injected areas was used as a control.
