Injuries can sideline athletes for a long time, especially when it's a torn ACL or muscle. It won't have to be like that for long. Researchers at the Worcester Polytechnic Institute in Massachusetts have developed a technique that could speed up muscle regeneration immensely.
Associate Professor George Pins and his team implanted injured mice with microthreads coated with human cells. The threads are made of fibrin, the same protein used by the body to repair wounds, and act as a scaffold during the healing process, helping to properly align the muscle tissue.
So far, the mice showed strong signs of recovery, and within 10 weeks, their injuries were chock-full of human muscle. Pins and company's next step is to confirm if the new hybrid muscles will behave properly.
