Breakthrough in 3-D printing for spinal cord repair

University of Minnesota researchers have broken new ground in the rapidly advancing field of 3-D printing: Creating stem cell-infused scaffolds that could be implanted in spinal cords to repair nerve damage.

The technology has existed for years to print plastic implants containing live cells. But the challenge was to do so in a way that would allow sensitive "neuronal" stem cells to survive the printing process so they can repair nerve damage after transplant.
