Myogenesis is the formation of muscular tissue, particularly during embryonic development. Muscle fibers generally form from the fusion of myoblasts into multi-nucleated fibers called myotubes. In the early development of an embryo, myoblasts can either proliferate, or differentiate into a myotube. What controls this choice in vivo is generally unclear.

In February 1935, Wagner introduced the National Labor Relations Act in the Senate. The Wagner Bill proposed to create a new independent agencyâthe National Labor Relations Board, made up of three members appointed by the President and confirmed by the Senate-to enforce employee rights rather than to mediate disputes.
