First, researchers used soap to wash out most of the cells from a rat's heart. Then they injected new cells to the shell that was left and added a pacemaker to teach the cells to pump like a heart. The result was a new heart. The process -- likened to gutting and rebuilding a house -- may take scientists a step closer to offering new options to the sickest patients.
