Scientists have discovered that a specific protein in slow-twitch muscles is essential for regulating the body's blood sugar, ...

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 ...

The mechanical environment of smooth muscle cells and the surrounding extracellular matrix orchestrates vascular tone, tissue remodelling and pathology. Smooth muscle cells reside within a fibrous ...

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 ...

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 ...

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 ...

Microtubules, part of heart muscle cells' internal "skeleton," help determine how the heart changes shape under stress, and a ...

A new study shows that people with type 2 diabetes have lower levels of the protein that breaks down and converts creatine in the muscles. This leads to impaired function of the mitochondria, the ...
