Every cell in the human body carries the same 3 billion letters of DNA, yet a neuron, a heart muscle cell and a pancreatic beta cell each use that shared code to do entirely different jobs. How cells ...

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

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 ...

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

Before testing new therapies in animals, researchers now have a more efficient starting point—lab-grown canine muscle cells that can help identify what works and what doesn't. Developed at the Texas A ...
