3D-Bioprinting Technique Produces Viable Blood Vessels in Monkeys

In 2015, Chinese biotechnology company Revotek released a 3d-bioprinter that fabricates blood vessels using a bio-ink made from stem cells. Just before the close of 2016, Kang Yujian, chief scientist and CEO of Revotek, announced the first successful transplant of bioprinted blood vessels into the abdominal aortas of 30 rhesus monkeys. All monkeys have survived thus far and the 3d-printed biomaterial has achieved regeneration of the endothelial and muscle cells that compose authentic blood vessels. The success of this experiment could one day have far reaching implications for the nearly two billion patients with cardiovascular disease.
