How to boost muscle regeneration and rebuild tissue

Induction of Yamanaka factors (OKSM) in muscle fibers increases the number of myogenic progenitors. Top, control; bottom, treatment. Red-pink color is Pax7, a muscle stem-cell marker. Blue indicates muscle nuclei.

Clues about molecular changes underlying muscle loss tied to aging. In work that could one day help athletes as well as aging adults regenerate tissue more effectively, scientists increased the regeneration of muscle cells in mice by activating the precursors of muscle cells.

One of the many effects of aging is loss of muscle mass, which contributes to disability in older people...
