flag Scientists used 3D-printed scaffolds to help paralyzed rats regain movement, a step toward treating human spinal injuries.

flag Researchers are using 3D printing to create scaffolds with microscopic channels that guide nerve cell growth in spinal cord injuries. flag Combined with stem cells and lab-grown tissues, these scaffolds helped rats with severed spinal cords regain movement and function. flag The technology aims to repair damage by reconnecting nerve pathways, offering potential future treatments for spinal cord injuries in humans.
