Researchers isolate a master heart cell

Posted Nov 23, 2006 by Bob Norman

Harvard scientists have discovered a single type of cell that builds the three main types of heart tissue,
The team identified the heart cell in mice, and proved that it develops into the muscle cells that power the heart, the cells that make up blood vessels, and the smooth muscle cells that allow the vessels to expand and contract.
If the human equivalent of the new cells is found, it could be given to patients to rebuild heart tissue that cannot be repaired today. The work could also give biologists new tools to look for heart drugs.
If science had a way to fix heart problems without replacement surgery it would give hope to so many patients for whom surgery isn't an option. This is a promising development.
