Muscles of the elderly and of patients with Duchene muscular dystrophy have trouble regenerating. A new nanohydrogel with muscle stem cells has boosted muscle growth in mouse models while protecting the stem cells from immune reactions that usually weaken or destroy them. 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.

Researchers at the Georgia Institute of Technology engineered a molecular matrix, a hydrogel, to deliver muscle stem cells called muscle satellit...
