Spinal cord repair and recovery of motor function after injury could one day be a possibility with a new hydrogel platform developed by researchers in China.

When the spinal cord is completely severed, neural connections as well as blood supply are interrupted, leading to paralysis. To improve the outcomes for spinal cord repair, researchers implanted a photosensitive hydrogel in a rat model of spinal cord injury. The hydrogel scaffold continuously and slowly released Taxol and collagen-binding stromal derived factor (SDF)-1alpha, two compounds that work synergistically to repair the spinal cord.
