Scientists in Israel unveiled a 3D print of a heart with human tissue and vessels on Monday.

While it remains a far way off, scientists hope one day to be able to produce hearts suitable for transplant into humans as well as patches to regenerate defective hearts.
The heart produced by researchers at Tel Aviv University is about the size of a rabbit's.
It marked "the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers," said Tal Dvir, who led the project.
"People have managed to 3D-print the structure of a heart in the past, but not with cells or with blood vessels," he said.
But the scientists said many challenges remain before fully working 3D printed hearts will be available for transplant into patients.
