Protein TRF2 Found Crucial for Muscle Stem Cell Repair and Identity

Researchers at the University of Pennsylvania's Perelman School of Medicine have discovered that the protein TRF2, previously known for chromosome protection, is vital for maintaining muscle stem cell identity and coordinating muscle repair. This finding could lead to new treatments for muscular dystrophy and offers insights into cancer biology, as TRF2 helps preserve genetic instructions for tissue regeneration.
