New views of intracellular channel that controls skeletal muscle

Using high-resolution electron microscopy, Columbia University Medical Center (CUMC) researchers have uncovered new details of the structure and function of an intracellular channel that controls the contraction of skeletal ...

Learning how muscle cells feel the pull of gravity

People can easily feel the presence - or absence - of gravity. Our individual cells actually may be able to sense gravity, too, and that ability could play a role in the loss of muscle that occurs when humans spend time in ...

First contracting human muscle grown in laboratory

In a laboratory first, Duke researchers have grown human skeletal muscle that contracts and responds just like native tissue to external stimuli such as electrical pulses, biochemical signals and pharmaceuticals.

Muscle-powered bio-bots walk on command (w/ Video)

(Phys.org) —A new generation of miniature biological robots is flexing its muscle. Engineers at the University of Illinois at Urbana-Champaign demonstrated a class of walking "bio-bots" powered by muscle cells and controlled ...

Stem cell clues uncovered

Proper tissue function and regeneration is supported by stem cells, which reside in so-called niches. New work from Carnegie's Yixian Zheng and Haiyang Chen identifies an important component for regulating stem cell niches, ...
