Sarcopenia—reduced muscle mass, strength, and function—is often associated with aging and frequently impacts quality of life in the elderly. Individuals with sarcopenia are also prone to further ...

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) ...

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 ...

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

As we age, the muscles we rely on for daily activities tend to become less reliable. With enough decline, even normal movements such as getting out of bed become risky. Low muscle mass in the ...

As muscles age, their cells lose the ability to regenerate and heal after injury. Cornell Engineering researchers have created the most comprehensive portrait to date of how that change, in mice, ...

The production of cultured meat depends on the isolation, expansion, and differentiation of animal stem cells into edible tissues. Muscle stem cells, or satellite cells, are central to this process ...

“Our findings suggest that hibernating animals do not simply tolerate muscle damage during winter. Instead, they actively suppress muscle repair in a controlled and reversible way,” Miyazaki explains.
