T he 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 ...

Breakthrough discovery sheds light on heart and muscle health Scientists shoot first true-to-life 3D image of the thick filament of mammalian heart muscle ...

The heart is a muscular organ made up mostly of cardiac muscle, which is specific to the heart. The function of the heart is to pump blood to the rest of the body, so it's very important to keep ...

Cardiac muscle really knows how to relax: Potential cardio-protective mechanism in heart Date: April 21, 2011 Source: Cell Press Summary: New insight into the physiology of cardiac muscle may lead ...

In the short-term, the death of cardiac muscle cells can cause a critical drop in the heart's ability to function. Over the long haul, problems arise because the damage is largely repaired by scar ...

Skeletal muscles, which make up around 50% of our body weight, are striated, but so too are cardiac muscles, which control heartbeats. Another type of muscle, smooth muscle, also consists of thin ...

Heart organoids have even been sent to space to test the effect of microgravity on cardiac muscle. But there's a tiny problem—the organoids can't grow any bigger than a sesame seed.

Lapidos and colleagues write that pluripotent bone-marrow-derived side population stem cells have been shown to repopulate the hematopoietic system and to contribute to skeletal and cardiac muscle ...

Researchers have identified a crucial growth factor, BMP7, capable of stimulating cardiac muscle cell proliferation and regeneration, potentially offering new treatments for heart injuries. This ...
