Columbia Engineering researchers have shown, for the first time, that electrical stimulation of human heart muscle cells (cardiomyocytes) engineered from human stem cells aids their development and ...

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 ...

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 ...

Diseased hearts may be thrown out of rhythm by structural differences -- now visible for the first time -- in protein groups that connect heart muscle cells, according to the authors of a study to be ...

Scientists may have discovered another way the human body tries to protect itself from cancer. New research on mice suggests that the heart's constant beating may prevent tumor growth in cardiac ...

Heart muscle cells grown from patient stem cells—known as human induced pluripotent stem cell–derived cardiomyocytes, or hiPSC-CMs—are a promising way to repair hearts damaged by heart attacks and ...

A UC San Diego–led team has discovered that restoring a key cardiac protein called connexin‑43 in a mouse model can dramatically improve heart function and extend survival in several inherited forms ...

In research, induced pluripotent stem (iPS) cells are derived from skin, urine, or blood samples and developed into other cells, like heart tissue, that researchers want to study. Because of the ...
