Injection of normal adult superior rectus with Botox resulted in a significant increase in the number of MyoD-positive satellite cells (arrowheads) compared with the normal EOM. Normally, the myonuclei in adult skeletal muscle are negative for MyoD expression. However, Botox treatment resulted in the appearance of MyoD-positive myonuclei, which were randomly located throughout the treated muscle (arrows).
