The promise of a stem cell “patch” to treat cardiovascular disease may be closer to reality as scientists continue to test the device in animals, a necessary step prior to embarking on a human trial.
In theory, the heart patches, engineered tissue composed of the several different types of cells that make up heart muscle, would be implanted to replace diseased or damaged tissue and would perform all the functions of healthy, beating heart muscle, say researchers at the University of Wisconsin-Madison.
