UCLA Scientists Uncover Protein Hindering Muscle Repair in Aging

Researchers at UCLA have identified a protein, NDRG1, that accumulates in older muscle stem cells, impeding their ability to repair tissue after injury. This finding clarifies why muscle healing slows with age, offering a new understanding of the biological processes involved. The discovery, published in Science, also suggests a potential target for future therapies aimed at rejuvenating muscle repair.
