A team of engineers and medical researchers from the University of Minnesota (UMN) are working on creating Neural Scaffold that can help patients with spinal cord injury alleviate pain and gain control over functions like bladder, bowel, and muscle control again. The prototype contains 3D Printed Silicone Guide acts as a scaffold, over which neuronal stem cells are 3D Printed, which then later differentiate into neurons, and then it is implanted into the injured part of spinal cord.
