Scientists Have Opened the Door to Biological Pacemaker Ther
Throughout life each heart beat is regulated primarily by a specialized tissue called the sinoatrial node. Unfortunately, this natural pacemaker’s ability to maintain the heart rate properly can be disrupted by a number of issues including congenital defects, aging, or ischemic heart disease. Recent work produced by researchers in Dr. Gordon Keller’s lab at the University of Toronto may lead to new therapies based on natural pacemaker cells grown in the lab. These human pacemaker-like cells had the ability to generate electricity spontaneously and were able to pace a rat heart after being implanted for 2 weeks...
