Functional and molecular regeneration in mdx muscle with matrix treatment. Functional and molecular regeneration in mdx muscle with matrix treatment. (A,B) Matrix-treated mdx mice were able to run at greater speeds (A) and greater distances (B) than PBS-treated littermates. (C) Early- and mid-stage myogenic gene transcription was also increased with matrix treatment compared with untreated contralateral muscle. *P≤0.05 versus PBS; **P≤0.02 versus all other treatments.
