Study identifies a 'sensor' that activates cell migration

The cytoskeleton is a structure that not only helps cells maintain their shape and internal organisation, but also enables them to perform functions like movement and migration to sites far from the place where they originated. ...

The mechanics of life

An interdisciplinary research team formed by Otger Campàs, assistant professor in the Department of Mechanical Engineering at the University of California, Santa Barbara (UCSB), and colleague Jérome Gros, group leader the ...

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.

Signal gradients in 3-D guide stem cell behavior

Scientists know that physical and biochemical signals can guide cells to make, for example, muscle, blood vessels or bone. But the exact recipes to produce the desired tissues have proved elusive.

Dip chip technology tests toxicity on the go

From man-made toxic chemicals such as industrial by-products to poisons that occur naturally, a water or food supply can be easily contaminated. And for every level of toxic material ingested, there is some level of bodily ...
