“…40 Compared to controls, a significantly reduced MSTN expression could have recently been observed in the masticatory muscles of 100-day-old dystrophic mice. 21 In the complete regenerated muscle in the mdx mouse after 9 weeks of birth, there was no evidence of myostatin. 40 Based on our findings, one can act on the assumption that regenerative processes in the masticatory muscles of the mdx mouse after BTX-A injection in the right masseter muscle were highly activated in these mice, which usually cannot be found at this age.…”
