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 ...

In a recent study published in the journal Nature, a large team of researchers from the United States (U.S.) used single-cell ribonucleic acid (RNA) sequencing combined with high-resolution ...

A Johns Hopkins-led study reports that severe obesity in people with heart failure with preserved ejection fraction (HFpEF) is linked to weakened contraction of heart muscle cells, but this defect may ...

Losing muscle strength is a natural part of aging. At the core of this decline is a drop in the number of muscle stem cells ...

A muscle patch crafted from stem cells has improved cardiac function in monkeys with heart disease. It is now being tested in a small number of people, with early results from the first recipient ...

The next time you train, remember: You’re not just building endurance. You’re upgrading your heart's software. You're rewriting the molecular code of what it means to survive, adapt — and thrive.
