Tiny Lab-Grown Spinal Cords Could Hold the Key to Healing Paralysis

Researchers have created a remarkable new approach to repairing spinal cord injuries by merging 3D printing, stem cells, and lab-grown tissues. They engineered tiny scaffolds that guide stem cells to form nerve fibers capable of bridging severed spinal cords. In experiments with rats, this method restored nerve connections and movement, offering new hope that one [...]
