For many patients who survive a heart attack, recovery is only the beginning. Structural and functional changes in the heart ...

Two research teams at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) have developed a pioneering technique in Spain to characterize the proteome of individual cardiomyocytes ...

Over the course of evolution, the human heart has largely lost its ability to regenerate. Our distant ancestors were not afflicted by heart attacks—a condition that emerged primarily with modern ...

Researchers mapped 442,239 single nuclei from nonfailing human hearts to chart how cardiac cells change from fetal ...

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 ...

For decades, biologists assumed a cell's energy simply diffused to wherever it was needed. It turns out the most important destination of all has a private delivery line.

Researchers have uncovered a molecular pathway that appears to block kidney regeneration after injury. The body’s ability to ...

Deep inside a small, windowless room at the University of California, Berkeley, two microscopes are quietly capturing some of ...

This video explains how the heart, blood, and blood vessels work together to circulate oxygen, nutrients, and other vital ...

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 ...

Healthy sleep and regular exercise can work to counteract genetic mutations in white blood cells that are associated with cardiovascular disease and are most common among older people, Mount Sinai ...
