Losing muscle strength is a natural part of aging. At the core of this decline is a drop in the number of muscle stem cells (MuSCs), the specialized cells responsible for maintaining and regenerating ...

As we age, our muscles atrophy. Earlier this year, researchers found that hepatocyte growth factor (HGF), a protein critical in skeletal muscle development loses its functionality due to nitration as ...

Musculoskeletal disorders are a primary cause of disability worldwide, especially in aging societies like Japan. As individuals age, reductions in muscle mass and physical activity weaken the body's ...

A new research paper was published in Volume 18 of Aging-US on May 15, 2026, titled “Extracellular vesicles released by ...

Before testing new therapies in animals, researchers now have a more efficient starting point—lab-grown canine muscle cells ...

Muscle tissue from aged mice seven days after injury. Left: Aged mice with normal NDRG1 levels show slower regeneration with smaller muscle fibers. Right: Aged mice in which NDRG1 was recently blocked ...

Researchers typically create organoid models for other biological systems with pluripotent stem cells, but the Harvard team began with readily accessible myoblasts, which satellite cells differentiate ...

Liz covers cardiovascular and metabolic disease, asking why we’re not doing better or even losing ground against the world’s leading killer. Send tips on Signal at LizC.22. By its name and nature, ...

A research team has found that specific immune cells can connect with muscle fibers in a lightning-fast, neuron-like way to promote healing. These cells deliver quick pulses of calcium, triggering ...
