Thirty marks the spot. Starting at this age, we begin to lose approximately three to eight percent of muscle mass per decade. With it, we also lose strength and mobility. Left unaddressed, this loss ...

Scientists at UCLA discovered a surprising reason aging muscles heal more slowly. In older muscle stem cells, a protein called NDRG1 builds up and acts like a brake, slowing the cells’ ability to jump ...

Muscle-on-chip systems are three-dimensional human muscle cell bundles cultured on collagen scaffolds. A Stanford University research team sent some of these systems to the International Space Station ...

The population across developed countries is getting older and the associated frailty and debilitation are becoming major health problems. This gradual muscle loss is accelerated by the poor capacity ...

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 ...

When bones break and there is extreme tissue loss--such as after a car accident or a battlefield injury--current treatments don't often lead to effective healing. But certain stem cells from skeletal ...

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 ...

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 ...

A Northwestern Medicine study has uncovered how chronic defects in muscle membrane repair can fuel harmful inflammation. The ...

Skeletal muscle organoids help scientists bypass bottlenecks in satellite cell production for muscle regeneration research. Researchers typically create organoid models for other biological systems ...
