The study published in the journal PLOS Biology showed TTK21 aided the regrowth of sensory and motor neurons when given to mice 12 weeks after severe injury.Retraction of motor axons above the point of injury was also halted, and sensory axon growth increased.SIMILAR: Movement in Paralyzed Arms is Restored by ‘Zapping’ Spinal Cords With Electrical StimulationThe next step will be to boost the effects even more and get regenerating axons to reconnect to the rest of the nervous system so animals can regain their ability to move with ease.RELATED: First Time Someone With Cut Spinal Cord is Able to Walk Freely, Thanks to New Swiss TechnologyIn the U.S., an estimated 300,000 people and another 50,000 in the UK are living with a spinal cord injury.Last year GNN reported that Yale had used stem cells to repair patients’ injured spinal cords, which could be another future avenue to repairing nerves and axons."
