Ars Technica reports Scientists regenerate spinal cord in injured rats with stem cells "While previous studies have shown progress in regenerating certain types of nerve cells in injured spinal cords, the study is the first to coax the regrowth of a specific set of nerve cells, called corticospinal axons. These bundles of biological wiring carry signals from the brain to the spinal cord and are critical for voluntary movement. In the study, researchers were able to use stem cells from rats and humans to mend the injured rodents."
