Aging muscles heal more slowly after injury—a frustrating reality familiar to many older adults. A UCLA study conducted in mice reveals an unexpected cause: Stem cells in aged muscle accumulate higher ...

When a car accident or athletic injury destroys more than 20% of a muscle's mass, the body faces a problem it often can't ...

Key takeaways UCLA researchers studying mice discovered that stem cells in aged muscle accumulate a protective protein called NDRG1 that slows their ability to repair tissue but helps the cells ...

As people age, muscles naturally lose mass and strength, a condition known as sarcopenia. The decline can make everyday activities harder and increases the risk of falls, disability and early death.

In simple terms, stem cells that don’t build up enough of the NDRG1 protein eventually die off. What remains is a group of cells that repair muscle more slowly but are tougher and more resilient, able ...

Having different chronotypes, or being more active in the morning vs. afternoon, may play an important role in preserving muscle mass and strength, and metabolic health, according to a new study.
