Synthetic Matrix Delivers Healing Stem Cells To Injured Aged Muscles

Researchers examined a molecular matrix, a hydrogel, to deliver muscle stem cells called muscle satellite cells (MuSCs) directly to injured muscle tissue in patients whose muscles don't regenerate well. In lab experiments on mice, the hydrogel successfully delivered MuSCs to injured, aged muscle tissue and boosted the healing process while protecting the stem cells from harsh immune reactions.

A car accident leaves an aging patient with severe muscle injuries that won't heal. Treatment with muscle stem cells from a donor might restore damaged tissue, but doctors are unable to deliver them effectively. A new method may help change this. The study was published in the journal Science Advances
