heart cells

In flies and mice, a viral protein increases the rate of energy use by heart cells. But it’s not yet clear if the finding applies to humans.

Specialized immune cells generated in vivo reduce cardiac scar tissue in mice, a new study shows.

There is little evidence that antihypertensive drugs worsen COVID-19, and scientists are instead exploring the idea that such medications—or their downstream effects—may actually alleviate symptoms.

A case study of a family demonstrates that different genetic mutations from the two parents cause severe heart disease symptoms in the children.

CRISPRed heart muscle cells from humans gain the ability to make a protein missing in Duchenne muscular dystrophy.

By zooming in on a developing mouse heart, scientists are studying whether defects in vasculature contribute to a thin muscle wall.

Maps of diving cells before and after heart attacks in mice offer additional evidence against the existence of cardiac stem cells.

A mouse study adds to the growing body of work disputing the ability of progenitor cells to regenerate muscle tissue in adult mammals’ hearts.

Having pioneered the study of muscle physiology in mammals, she uncovered how ion channels enable muscle movement.

Researchers created a nanofibrous scaffold to see how it supports cell growth.

A failing heart is easily distinguished from a healthy one by numerous tell-tale signs, including its slender, stretched-out walls, increased size, and pooled blood clots.
