Researchers Develop Novel 3D Bioprinting Platform to Aid Natural Cell Function Preservation

Published in Bioprinting.

A collaborative study headed by Professor Xiujie Wang at the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, Professor Charlie Wang C. L. at The University of Manchester, and Professor Yongjin Liu at the TsingHua University, has announced a novel three-dimensional (3D) bioprinting platform.

3D bioprinting, which integrates a 3D printer with bioinks (frequently consisting of biomaterials and cells) to fabricate tissue- or organ-mimicking structures, is one of the most hopeful technologies for in vitro human organ generation.

But the commonly utilized 3D bioprinting method is incapable of integrating blood vessel networks at the time of the bioprinting process and thus experiences difficulty when fabricating functional and long-lived complex organs as a result of the lack of nutrient supply to printed cells.
