The ability to breathe has been restored to mice with spinal cord injuries, in what US researchers describe as a medical first.
Some patients with damaged spinal cords need ventilators as they are unable to breathe on their own.
A report in the journal Nature showed a nerve graft, coupled with a protein, could restore breathing.
Human trials could begin soon, which the charity Spinal Research said could be "potentially life-changing".
Damage at the top of the spinal cord, around the neck, can interrupt messages to the diaphragm - a layer of muscle involved in breathing.
