To determine if CEP-701 treatment enhances engraftment capacity, we isolated primary satellite cells from C57BL/6-β-actin-EGFP mice [19], expanded them in vitro for 5 days in the presence of 50 nM CEP-701 or vehicle, and transplanted 30,000 expanded donor GFP+ cells into regenerating CTX-damaged TA muscle of 6–8-week-old mdx mice, a model of Duchenne muscular dystrophy [20] (Fig. 3e). This evidence concerns the gene ACTB and Duchenne muscular dystrophy.
