Importance of Satellite Cells in Muscle Development
Satellite cells play an extremely vital role in muscle development. In all animals, the number of muscles and the number of muscle fibers are predetermined before birth. When a baby is born, the number of muscles and muscle fiber does not grow but only matures. Like other types of cells, muscle cells degenerate and get damaged due to everyday life. Satellite cells sole responsibility is to help recruit myonuclei and regenerate damaged muscle cells.
The origin of satellite cells is unclear. Originally, scientists believed that they were derived from somite cells or remnants of fetal myoblasts. More recently, scientists are finding evidence that leads them to believe that the cells have non-somite origin. These scientists believe that other cell types serve as templates and under certain conditions, they differentiate into satellite cells. Due to the difficulty in obtaining satellite cells, research is very difficult......
