“This is an early but exciting step toward recharging aging tissues using their own biological machinery,” Gaharwar says in ...

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 ...

Companion studies suggest muscle begins to decline decades before sarcopenia takes hold for keeps. The best part: The process ...

Skeletal muscle stem cells in hibernating Syrian hamsters preserve their ability to function by suppressing their activation ...

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 ...

“For many cell-based therapies, progress comes from connecting the right pieces at the right moment,” Klein said. “When ...

As people age, muscles naturally lose mass and strength, a condition known as sarcopenia. The decline can make everyday ...

Stem cells that live in the muscle impart its ability to regenerate. After an injury, muscle stem cells activate and must expand in number to repair and make new muscle (marked by dystrophin in white) ...

Cartilage is the body’s most stubborn tissue. Once it wears away, it’s usually gone for good. This biological dead-end is the ...
