3D-Printed Implant Promotes Nerve Cell Growth to Treat Spinal Injury

The implants, described in a study published in the January 14 issue of Nature Medicine, are intended to promote nerve growth across spinal cord injuries, restoring connections and lost function. In rat models, the scaffolds supported tissue regrowth, stem cell survival and expansion of neural stem cell axons out of the scaffolding and into the host spinal cord. "In recent years and papers, we've progressively moved closer to the goal of abundant, long-distance regeneration of injured axon...
