How do Myonuclei Contribute to Muscle Fiber Type Differentiation?
Skeletal muscles are composed of different types of muscle fibers, such as Type I fibers (slow-twitch) and Type II fibers (fast-twitch). Myonuclei contribute to the specialization of these fibers by regulating the expression of specific genes that define the characteristics of each fiber type. This specialization is crucial for the muscle's ability to perform a wide range of functions, from endurance activities to rapid, powerful movements.
