Scientists turn fat cells into muscle?

Stem cells taken from human fat can be transformed into smooth muscle cells, offering a way to treat diseases of the heart, gut and bladder, US researchers report. While the experiment does not quite offer a way to turn a pot belly into a flat stomach, the researchers say the transformed cells contracted and relaxed just like smooth muscle cells. These cells help the heart beat and blood flow, push food through the digestive system and make bladders fill and empty, the researchers report. Unfortunately, this research won't turn a pot belly into a flat stomach.
