Skeletal Muscle Satellite Cells

Skeletal muscle satellite cells are specialized stem cells located on the surface of muscle fibers. They play a crucial role in muscle growth, repair, and regeneration. When muscles experience injury or stress, these cells become activated, multiply, and fuse with existing muscle fibers to help repair damage. They also contribute to muscle hypertrophy, or growth, by generating new muscle cells. Satellite cells remain in a resting state during normal conditions but are ready to activate when needed, making them essential for maintaining healthy, functional muscle tissue throughout life.
