Discovery of a 'conductor' in muscle development could impact on the treatment of muscular diseases

A 'conductor' has been discovered in the development of muscle tissue. The discovery could have an important impact on the treatment of muscular diseases such as myopathies and muscular dystrophies. The fusion of myoblasts is a critical step in the formation of embryonic muscle fibers as it determines muscle size, among other things. This process is also important in adult life because muscle stem cells fuse with existing fibers to achieve muscle growth and help regenerate damaged muscles. Howev...
