"When we saw the first contractions we were speechless." - Dr. Doris Taylor Scientists from the University of Minnesota have successfully created a beating heart in a lab. The team was led by Dr. Doris Taylor, director of the University's Center for Cardiovascular Repair, used a process called "decellularization" in which the hearts were taken from newborn rats and stripped of their cells. The resulting non-living masses, called extracellular matrices or ECMs, contain no cells and therefore will not be rejected by its new owners. New muscle and endothelial cells were then injected into the ECM and stimulated electrically.
