“Dancing Molecules” Successfully Repair Severe Spinal Cord Injuries; After Single Injection of Short Modified Peptides that Mimic the Motion of Biological Molecules, Paralyzed Animals Regained Ability to Walk within Four Weeks

Northwestern University investigators have developed a new injectable therapy that harnesses “dancing molecules” to reverse paralysis and repair tissue after severe spinal cord injuries. In the new study, published in the November 11, 2021 issue of Science, investigators administered a single injection to tissues surrounding the spinal cords of paralyzed mice. Just four weeks later, the animals regained the ability to walk. The article is titled “Bioactive Scaffolds with Enhanced Supramolecular Motion Promote Recovery from Spinal Cord Injury.”
