Spinal Cord Injury and Paralysis, including Stroke


Paralysis is defined as a central nervous system disorder resulting in difficulty or inability to move the upper or lower extremities.

Read more below about how stem cell research is helping in the fight against paralysis and spinal cord injuries.

About

  • The most recent data reveal:
    • Nearly 1 in 50 people in the United States lives with paralysis, making up almost 5.4 million people or 1.7% of the US population.
    • Leading causes of paralysis, in order of incidence rate, are stroke (33.7%), spinal cord injury (27.3%), and multiple sclerosis (18.6%).
    • Only 15.5% of individuals living with paralysis are employed, and 41.8% of individuals with paralysis report that they are unable to work.
    • Causes of spinal cord injury, in order of incidence are motor vehicle accidents, physical labor, falls, sports accidents, and victims of violence.
    • Spinal cord injury alone cost the country roughly $40.5 billion per year, a figure that has increased 317% since 1998.

How Stem Cell Research Can be Used to Treat Paralysis


CIRM’s Progress: Selected Research Highlights

  • CIRM has funded three clinical trials that affect paralysis:
    • One in stroke
    • Two in spinal cord injury
  • In a Phase 1/2 clinical trial, researchers at Lineage Cell Therapeutics use stem cells to generate oligo progenitors — the cells that protect nerves by keeping them insulated and ready for signal transmission. Notably, 96% of the patients enrolled in this trial have shown at least one level of motor recovery at 12 months post-transplantation.
  • In a Phase 2 clinical trial, researchers at SanBio isolated mesenchymal stem cells from the bone marrow of healthy adult donors, modified them to secrete “food” for existing nerve cells in the brain, and transplanted them after stroke. While the transplantation was shown to be safe, this study did not meet its primary endpoints. However, ongoing work using the same cell population may be leading to Phase 3 clinical trials in Traumatic Brain Injury.
