Replacement cartilage can grow in any shape with 3D-printed "spheroids"
Researchers at TU Wien have developed a new way to grow cartilage from stem cells and guide it into basically any shape required. The breakthrough could lead to better ways to patch up injuries.
But as important as it is, it has almost no regenerative ability in adults, so when it’s damaged due to injury or just decades of wear-and-tear, it can lead to painful chronic conditions like osteoarthritis. For the new study, the TU Wien team developed a technique that can grow samples of cartilage into basically any shape needed, which they demonstrated by forming it into the university’s logo. The spheroids are made of a biocompatible plastic material, which provides stability and structure in the beginning, but breaks down over a few months, leaving behind the tissue in the desired shape.
