As 3D bioprinting continues to advance, there are still challenges that plague most methods of 3D printing tissue. One of those challenges involves properly positioning the 3D printed cells within their scaffolds so that the structures don't collapse on themselves. But a group of researchers at the University of Oxford have developed a new method of bioprinting that involves self-contained, self-supporting cells.
