Satellite cells are muscle stem cells that play a crucial role in muscle growth, régénération, et réparation. These cells are located between the sarcolemma and the basal lamina of muscle fibers and are responsible for maintaining and repairing muscle tissue.
Satellite Cells: The Building Blocks of Muscle Growth
Satellite cells are essential for muscle growth and hypertrophy. When stimulated by exercise or other factors, these cells become activated and begin to proliferate and differentiate into new muscle fibers. This process is known as myogenesis and is responsible for the increase in muscle mass that occurs with regular exercise.
The Role of Satellite Cells in Muscle Regeneration and Repair
In addition to their role in muscle growth, satellite cells also play a vital role in muscle regeneration and repair. When muscle fibers are damaged or injured, satellite cells become activated and migrate to the site of injury. They then proliferate and differentiate into new muscle fibers, which help to repair the damaged tissue and restore muscle function.
