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

For the first time, researchers at University of California San Diego School of Medicine and Institute of Engineering in Medicine have used rapid 3D printing technologies to create a spinal cord, then successfully implanted that scaffolding, loaded with neural stem cells, into sites of severe spinal cord injury in rats. 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. A 3D printed, two-millimeter implant (slightly larger than the thickness of a penny) used as scaffolding to repair spinal cord injuries in rats. The dots surrounding the H-shaped core are hollow portals through which implanted neural stem cells can extend […]
