Researchers create a new heart in the lab

University of Minnesota researchers created a beating heart in the laboratory by injecting fresh heart cells into a non-living rat heart matrix. Amazing stuff.
“In the United States alone, about 5 million people live with heart failure, 550,000 new cases are diagnosed every year, and 50,000 die waiting for a donor heart. The work is published online in the January 13 issue of Nature Medicine.”
