Collaborative study using Allen Spinal Cord Atlas finds previously overlooked cell type with implications for treating spinal cord injury and disease
SEATTLE, Sept. 15, 2011 /PRNewswire/ — The Allen Institute for Brain Science announced today the discovery of a new class of cells in the spinal cord that act like neural stem cells, offering a fresh avenue in the search for therapies to treat spinal cord injury and disease. The published collaborative study, authored by scientists from the University of British Columbia, the Allen Institute for Brain Science and The Montreal Neurological Institute and Hospital at McGill University and titled “Adult Spinal Cord Radial Glia Display a Unique Progenitor Phenotype,” appears in the open access journal PLoS One.
Rehabilitation facilities test robotic exoskeleton
David Leone left behind his familiar wheelchair, shifting himself onto a chair where a robotic external skeleton fitted to his 5-foot-11-inch frame sat waiting. Half a dozen people scurried around him, cinching Velcro straps tight around his legs and torso. He grabbed the handles of a walker, leaned forward, and hoisted himself to his feet.
Seven years after he last walked, Leone – paralyzed from the waist down – lifted his right foot and took a step, with the robotic technology moving his limbs.
The 37-year-old from Millis kept on going, racking up 284 steps in a 42-minute session this week at Spaulding Rehabilitation Hospital in Boston.
