Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle ...

A stem-cell-based "organ-on-a-chip" model of ALS mimics early biological changes seen in the degenerative disease.

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 ...

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

As people age, muscles naturally lose mass and strength, a condition known as sarcopenia. The decline can make everyday activities harder and increases the risk of falls, disability and early death.

- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...
