Researchers from the University of Northwestern, in the United States, and the Institute of Bioengineering of Catalonia (IBEC), develop a new injectable therapy that uses synthetic nanofibers to repair spinal cord lesions. Nanofibers, which contain ‘Dancing molecules’ effectively stimulate cellular receptors by promoting spinal cord regeneration. After a single injection, paralyzed animals treated with this new therapy were able to walk again in just four weeks. The article has been published in Science.
