The big problem with tendon injuries is that they repair leaving scar tissue, which is less elastic than the normal collagen found in healthy tendons. This leaves them prone to further damage. By injecting plasmid DNA into the torn ligaments and tendons, the researchers were able to see that blood vessels developed within the tissue and the tissue grew back without leaving scar tissue behind.
