Engineered heart completely matches the immunological, cellular, biochemical and anatomical properties of the patient. In a major medical breakthrough, Tel Aviv University researchers have “printed” the world’s first 3D vascularised engineered heart using a patient’s own cells and biological materials.

Until now, scientists in regenerative medicine – a field positioned at the crossroads of biology and technology – have been successful in printing only simple tissues without blood vessels.

“This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers,” says...

This month >4,000 Americans are on waiting list to receive a heart transplant. Researchers have used a new 3D bioprinting method to bioprint models of hearts, arteries, bones and brains out of biological materials. The work could one day lead to a world in which transplants are no longer necessary to repair damaged organs.

“We’ve been able to take MRI images of coronary arteries and 3D images of embryonic hearts and 3D bioprint them with unprecedented resolution and quality out of very soft materials like collagens, alginates and fibrins,” said Assoc Prof Adam Feinberg

“3-D printing of various materials has been a common trend in tissue engineering in the last decade, but unt...
