Physical force alone spurs gene expression

April 3, 2020

Cells will ramp up gene expression in response to physical forces alone, a new study finds. Gene activation, the first step of protein production, starts less than one millisecond after a cell is stretched - hundreds of times faster than chemical signals can travel, the researchers report.

The scientists tested forces that are biologically relevant - equivalent to those exerted on human cells by breathing, exercising or vocalizing. They report their findings in the journal Science Advances.

New Technique First Step to Stem Cell Specialization

June 22, 2014

The gap between stem cell research and regenerative medicine just became a lot narrower, thanks to a new technique that coaxes stem cells, with potential to become any tissue type, to take the first step to specialization. It is the first time this critical step has been demonstrated in a laboratory.

University of Illinois researchers, in collaboration with scientists at Notre Dame University and the Huazhong University of Science and Technology in China, published their results in the journal Nature Communications.
