Johns Hopkins Medicine scientists who arranged for 48 human bioengineered heart tissue samples to spend 30 days at the International Space Station report evidence that the low gravity conditions in ...

A few years ago, biomedical scientist Jonathan Tsui flew to Florida with unique baggage. He toted compact chambers—smaller than a cell phone—containing 48 bits of human heart tissue. Tsui brought the ...

Lab-grown hearts with immune cells develop atrial fibrillation after chronic inflammation, offering a new way to test ...

The human heart has been found to show signs of aging after a mere month in space. Heart tissue samples aboard the International Space Station (ISS) were discovered to beat only around half as ...

A team of researchers have developed a 3D-printed, biodegradable heart patch that seals holes in heart tissue and supports tissue regeneration, showing promise as a safer alternative to current ...

A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on ...

Internal organ tissues often don’t heal after illness or injury and lose some function, such as the heart after a heart attack. UCLA cardiologists have identified a protein that interferes with ...

Researchers have developed a way of bioprinting tissues that change shape as a result of cell-generated forces, in the same way that it happens in biological tissues during organ development. The ...

The body's tissues can get injured in many ways, but while some injuries heal perfectly, others don't heal at all. A cut in the skin, for example, usually heals all on its own, while internal organs, ...
