Developmental biologist Eric Olson, Ph.D., has discovered that the hearts of infant mammals are capable of regenerating and repairing themselves. This extraordinary capability is lost once mammals become adults. Olson, a professor of molecular biology at University of Texas Southwestern Medical Center, explains why adult hearts lose this ability and discusses his and others’ research on the possibility of cell regeneration in the adult heart so it can repair itself after an attack.
