How Do Myoblasts Contribute to Muscle Fiber Formation?
Once formed, myoblasts undergo a process called fusion to form multinucleated muscle fibers, known as myotubes. This process involves the alignment of myoblasts, followed by membrane fusion. The fusion process is regulated by various proteins, including dysferlin, myomaker, and myomerger. The newly formed myotubes further mature into myofibers, which are the functional units of muscle tissue.
