Effect of mRK35 on skeletal muscle fiber size in mdx mice. a Fiber area count at the mid-belly of the TA muscle harvested from mdx mice following 4 weeks of treatment with 10 mg/kg mRK35 or vehicle (n = 4 per treatment). b Representative cross-sectional images of the TA from vehicle-treated mice. c Representative cross-sectional images of the TA from mRK35-treated animals. Muscle fibers are stained with wheat germ agglutinin in green and counterstained with DAPI, which stains the nuclei, in blue
