Stem cell researchers in Hong Kong and the United States are trying to grow spare parts for the human heart that may be ready for tests on people within five years, they said on Thursday. Scientists have already made basic heart muscle from stem cells, but the Hong Kong-led team wants to refine it so it can replace any part damaged in heart attacks, and to recreate the natural pacemaker, where the heartbeat originates.
