Despite advances in emergency care and rehabilitation, no approved therapies exist to rebuild the neurons and connections lost after a spinal cord injury. But new research from scientists at Gladstone Institutes offers hope for a regenerative treatment in the future.

The study, published in Science Translational Medicine, shows that human stem cell-derived spinal interneurons—cells that are critical for breathing and movement—can survive after being transplanted in injured rats, connect with the animals’ own neural circuits and improve breathing-related motor function.
