Everyone has been high hopes for 3D bioprinting of human organs, but one of the biggest obstacles in this area is the printing of a functioning vascular system. Fortunately, researchers at the University of California, San Diego recently developed a functional vascular network using 3D bioprinting technology and applied it to mice. Researchers say their work will speed up the birth of artificial organs and regenerative therapies.
Chen's laboratory-developed 3D printed vascular network can be safely combined with the body's own network to transport blood. This research has been published in the journal Biomaterials. Chen and his team used a homemade 3D printer to cure a solution containing living cells and photopolymers with UV light to form a specific 3D shape. This method can produce 3D microstructures that mimic biological tissue in a matter of seconds, and has also been used to create liver tissue and 3D printed miniature fish that can deliver drugs in human blood.
In addition to other light curing or DLP (Digital Light Processing) 3D printing technology, in addition to being fast, another advantage of this UV bioprinting method is that the photopolymer used in the biological solution is very cheap, although it is completely Biocompatibility.
