Repairing severely damaged bone has been a very difficult task in the past for doctors and surgeons. Grafting bone from other parts of the body provides limited options, and trying to regrow bones with proper shape and size is even more tedious. However, researchers at Rice University are working to make the process easier with a gel that allows for targeted bone regeneration. The gel, made of biodegradable polymers, is combined with the patient’s stem cells. The gel is then placed where the new bone is needed, providing the patient not only with stem cells necessary for tissue regeneration, but a scaffold that encourages proper bone shape and degrades after solid tissue has regrown. For more information on Rice University’s gel, watch the video above.
