Hypertrophy is the process of increasing the number of cells within an organ or tissue (such as muscle tissue), thereby increasing its overall size.

The researchers believe that a decline in the number of these satellite cells and their functionality may prevent proper maintenance of muscle mass and its ability to repair itself, leading to muscle deterioration.
