WEDNESDAY, Sept. 17, 2025 (HealthDay News) — A new process that combines 3D printing, stem cells and lab-grown tissues could prove a groundbreaking innovation for spinal cord injury recovery, a new study says.

The process uses 3D printing to form stem cells into scaffolds containing microscopic channels that guide the growth of new nerve cells along the site of the spinal cord injury, researchers reported in Advanced Healthcare Materials .

“We use the 3D printed channels of the scaffold to direct the growth of the stem cells, which ensures the new ne
