Stem cells exist throughout the body and can form many types of cells. This makes them particularly valuable in exercising muscle cells, which turn over rapidly because of damage and repair.
Researchers from York University in Canada described the importance of stem cells in promoting muscle hypertrophy following weight training. High levels of muscle tension during resistance exercise damaged critical cell structures. Muscles contain satellite cells that migrate to damaged tissues, repair them, and increase muscle size.
Satellite cells maintain a balance between cell nuclei and muscle size, which is critical for cell health. Stem cells from other tissues stimulate muscle satellite cell activity and promote muscle growth. Cell maintenance and health in any tissue is extremely com
