Repairing Damage to Muscles May Be Matter of Getting Proteins to Trigger Stem Cells, Early Study Finds

A signaling pathway determines whether muscle stem cells differentiate and mature into working muscle cells, an early study in mice found. Targeting this pathway and its two proteins — Fam3a and Stat3, which works to stimulate Fam3a — may treat diseases or illnesses of muscles, including muscular dystrophies. Getting these stem cells to…
