Israeli Team Announces First 3D-Printed Heart Using Human Cells
"This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers," said team leader Tal Dvir.
The printer-generated heart is only about a third the size of an actual human heart -- and it doesn't actually work. But it's a groundbreaking step toward engineering customized organs that can be transplanted with less risk of rejection.
