        NOVA Next | Custom Organs, Printed to Order

        Learn how 3D bioprinting could alleviate organ shortages in this NOVA Next article. People in need of organ and tissue transplants face a number of obstacles, including long waiting lists and potential rejection. Researchers are working on methods to create synthetic organs using 3D bioprinting. One method uses a type of ink-jet printer filled with cells or proteins instead of traditional ink. Another method called stereolithography enables scientists to create a scaffold and coat it with cells to create the desired structure. Scientists are still navigating a number of challenges, from creating complex small-scale structures to maintaining blood flow. However, scientists hope to work through these issues to produce viable artificial organs. This resource is part of the NOVA Next Collection.
