Injectable Gel Helps Heart Muscle Regenerate
- Magazine Article
In mammals, including humans, the cells that contract the heart muscle and enable it to beat do not regenerate after injury.

With fewer of these contractile cells, known as cardiomyocytes, the heart pumps less blood with each beat, leading to the increased mortality associated with heart disease.
