National Science Foundation With a few flicks of a light switch--on-off-on-off--Stanford University's Oscar Abilez is one step closer to changing the lives of millions. Why? Because as a focused speck of light turns on and off in Abilez's lab, a cluster of heart cells begins to expand and contract. He demonstrates that he can control the rhythm of a heart using just light. Currently, 4 million Americans suffer from some degree of cardiac arrhythmia, wherein a person's heart beats too...

Heart Cells Turned Into Biological Pacemaker

Brett Smith for redOrbit.com - Your Universe Online Cardiologists from The Cedars-Sinai Heart Institute in Los Angeles have announced the development of a biologically-based pacemaker by reprogramming ordinary heart cells using the introduction of a single gene - Tbx18. "Although we and others have created primitive biological pacemakers before, this study is the first to show that a single gene can direct the conversion of heart muscle cells to genuine pacemaker cells. The new cells...

Artificial heart pacemakers have saved and extended the lives of thousands of people, but they have their shortcomings "“ such as a fixed pulse rate and a limited life. Could a permanent biological solution be possible? Richard Robinson and colleagues at New York's Columbia and Stony Brook Universities certainly think so, and their work published in the latest issue of The Journal of Physiology brings the dream a step closer to reality. The body's own natural pacemaker, called the...

Study points to longer-lasting treatment benefits for congestive heart failure Using pacemakers to electrically retune a heart damaged by long bouts of a wobbling heartbeat, where one heart muscle wall is beating sooner than the other, leads to fast improvements in the tissue levels of more than a dozen proteins key to the organ's health, scientists at Johns Hopkins report in experiments in dogs. The team's findings, published online this week in the journal Circulation, are believed to be...
