Key points from article :
UC San Diego has bio-printed a section of spinal cord in rats.
Could be custom-fit to a patient’s injury.
Small implants made of softgel 3D printed and filled with neural stem cells.
Surgically placed inside a tiny gap in the spinal cord.
New nerve cells and axons grew, forming connections across the gap.
Also connected with the hosts spinal cord tissue and the circulatory systems.
Cells that create scar tissue were reoriented.
The study was published in the journal Nature Medicine.
