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 ...

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 ...

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

FAPs reside in skeletal muscle, while superficial periosteal cells are found in the thin connective tissue called periosteum, ...

Researchers Sumika Kato, Takeo Kubo, and Taro Fukazawa of the University of Tokyo have discovered that c1qtnf3, a secreting factor, namely a protein molecule that is secreted by a cell and influences ...

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 ...

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 ...
