A group of scientist from Worcester Polytechnic Institute and CellThera regenerated functional tissue in mice by using a novel protocol to turn mature human muscle cells into a stem cell state. They grew those reprogrammed cells on biopolymer microtheads which were placed in a wound created by removing a huge section of leg muscle from a mouse. After awhile the threads and cells restored almost normal function to the muscle.

This is huge for people who have suffered from major muscle trauma! I think it’s amazing that a muscle can just regrow itself. This discovery can help thousands of people around the world, and changes some of the things we thought we knew about the human body.
