Scientists have taken a significant step towards bioprinting 3D organs for transplants. The team at the University of California, San Francisco, has developed an automated system that can print out and assemble complex structures from biological materials. The tool uses thin layers of a liquid pre-hydrogel solution which solidifies upon exposure to blue light, allowing scientists to develop biocompatible gels which can be moulded to accurately mimic the body's vascular networks.
Scientists have taken a significant step towards bioprinting 3D organs for transplants. Researchers from Rice University and the University of Washington have developed a tool which is able to print highly complex vascular networks that replicate those found in the body, one of the largest challenges in developing functional artificial organs. The tool uses thin layers of a liquid pre-hydrogel solution which solidifies upon exposure to blue light, allowing scientists to develop biocompatible gels which can be moulded to accurately mimic the body's vascular networks.
