This important study examines the role of pericytes in patterning the zebrafish blood-brain barrier (BBB) and controlling its permeability. Using pdgfrb mutant zebrafish models lacking brain pericytes ...

Yet over the month-long pilot study, “they were getting better and better.” Spinal muscle atrophy or SMA is a genetic disease that gradually destroys motor neurons, nerve cells in the spinal cord that ...

Newly discovered brain cells count each bite before sending the order to cease eating a meal. Columbia scientists have found specialized neurons in the brains of mice that order the animals to ...

This surge of fluids causes your muscle cells to swell up, making your muscles look larger than usual. When you get a muscle pump, it might feel like your muscles are "full," in a sense.

Sustainable engraftment of heart muscle cells (cardiomyocytes) can be achieved by implanting patches of engineered heart muscle onto the surface of the heart under immune suppression. Evidence ...

In 2009, Jonathan Weissman was hunting for a new way to spy on what happens inside a cell. In particular, the molecular cell biologist wanted to know what proteins are produced at any given moment.

Muscle strength grading is used to categorize muscle strength on a scale of 0 to 5 in relation to the expected strength for a muscle. One of the more common methods is a hands-on test called the ...
