myoblasts
(noun)
A type of embryonic stem cell that gives rise to muscle cells.
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.
