myoblasts

Examples of myoblasts in the following topics:

• Muscle Development

  • Muscle fibers form from the fusion of myoblasts into multi-nucleated fibers called myotubes.
  • The second stage involves the alignment of the myoblasts into the myotubes.
  • A myoblast is a type of embryonic progenitor cell that differentiates to form muscle cells.
  • Myoblasts that do not form muscle fibers dedifferentiate back into satellite (myosatellite) cells .
  • These long, tubular cells arise developmentally from myoblasts to form muscles.

• Somite Development

  • The myoblasts from the hypaxial division form the muscles of the thoracic and anterior abdominal walls.

• Capacity of Different Tissues for Repair

  • Activated satellite cells initially proliferate as skeletal myoblasts before undergoing myogenic differentiation.
