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 ...

Anatomically, cardiac rupture occurs at the intersection between injured and healthy cardiac tissue. This region is referred to as the borderzone. The conventional view is that increased mechanical ...

Study shows that cardiac spheroids, derived from human induced pluripotent stem cells, can be easily transported and injected into damaged areas of the heart to promote its regeneration and recovery ...

Researchers have harnessed a combination of lab-grown cells to regenerate damaged heart muscle. The study addresses major challenges of using heart muscle cells, called cardiomyocytes, grown from stem ...

Regenerative heart therapies involve transplanting cardiac muscle cells into damaged areas of the heart to recover lost function. However, the risk of arrhythmias following this procedure is ...

Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events. "This process appears to be regulated by myosin-binding protein-C (cMyBP-C), which ...

Researchers have developed a three-dimensional model that shows how exposure to cadmium might lead to congenital heart disease. Affecting nearly 40,000 newborns a year, congenital heart disease is the ...

The heart is the body's hardest-working muscle. Whether you're awake or asleep, or exercising or resting, your heart is always at work. It pumps blood through arteries to deliver oxygen to organs and ...
