Scientists use 3D printing to build better blood vessels

Bioengineers have been working on building lab-grown organs out of a patient's own cells, but one major challenges is to make blood vessels. Blood vessels deliver essential nutrients and dispose of hazardous waste to keep our organs working properly. Without them, interior cells quickly suffocate and die.

Now a team from Brigham and Women's Hospital in Boston, Massachusetts (BWH) has attempted to address this challenge by offering a unique method to create artificial blood vessels using hydrogel constructs that combine advances in 3D bioprinting technology and biomaterials.
