The human heart shrivels away in space, but researchers have found that mini-hearts grown from human stem cells sprout in ...

For the first time, scientists have shown that heart muscle cells can regrow after a heart attack in humans, a process that ...

When heart muscle gets damaged, the result is often permanent. Unlike other muscles in the body, the heart has long been believed to lack the ability to heal itself. But recent research suggests that ...

The heart is a very resilient muscle. Scientists observed heart muscle cells regenerating in mice studies after a heart attack. Their heart muscle cells, called cardiomyocytes, were observed dividing ...

A team of researchers led by Emory’s Chunhui Xu recently found that heart muscle cells can grow -and survive in the microgravity environment of space. Her findings, published in Biomaterials, show ...

A new study suggests severe obesity may weaken heart muscle cells in people with heart failure with preserved ejection ...

In a new research report, a team of scientists led by Johns Hopkins Medicine say people with severe obesity and a common type ...

The next time you train, remember: You’re not just building endurance. You’re upgrading your heart's software. You're ...

Can weight loss reverse heart failure? A new study shows that heart muscle cells regain strength and muscle contractions ...

Scientists obtained stem cells expressing cardiac muscle-specific genes and proteins. The cells displayed regular rhythmic contractions similar to a heart, confirming that they were functional ...
