Swedish researchers at Chalmers University of Technology and Sahlgrenska Academy have successfully induced human cartilage cells to live and grow in an animal model, using 3D bioprinting. The results will move development closer to a potential future in which it will be possible to help patients by giving them new body parts through 3D bioprinting. “This is the first time anyone has printed human-derived cartilage cells, implanted them in an animal model and induced them to grow,” says Paul Gatenholm, professor of biopolymer technology at Chalmers University of Technology.

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...
