Spinal cord injuries can result in severe neurological dysfunction, including motor, sensory, and autonomic paralysis, and up until now there has been no cure or effective treatment for such injuries.

But the first human trial based on Nobel Prize winning induced pluripotent stem cells (IPSC) technology, is due to start in Japan, giving hope to hundreds of thousands of paralysed patients, that there might be light at the end of their tunnel.

The spinal cord is responsible for relaying signals up and down the body from the brain to the nervous system. The spinal cord is a bundle of nerves contained in the spinal canal, which is cocooned in the spinal column (not to be confused with the spinal cord they are two very separate entities).

The spinal cord itself has a protective sheath wrapped around it which acts as insulation whilst allowing nerve signals from the brain to travel even faster to where they need to go.

The spinal column is divided into five distinct sections:

The site of the spinal cord injury will determine the severity of the injury and injuries are classified as either:

The higher up the spinal cord the injury occurs, the more function and feeling will be lost. It is estimated that approximately every year there are between 8 to 246 cases per million incidences of spinal cord injuries worldwide.

Stem cell therapy is amongst the most exciting ongoing research for people with spinal cord injuries, in modern medicine. Because whilst the research is still in its infancy, legitimate trials are showing promising results.

According to the Journal of the American Academy of Orthopedic Surgeons, there are different stem cells which have varying abilities to restore certain functions.

Stem cells are self-renewing cells that can differentiate into one or more specific cell types. For people with spinal cord injuries, stem cells could prevent further cell death, stimulate cell growth from the existing cells and even replace the injured cells, restoring the communication channels between the body and the brain.

Until recently, stem cell research has involved looking at:

It is research into these induced pluripotent stem cells that the team in Japan are currently laying down the groundwork for. They are planning to conduct a first-in-human study of an induced pluripotent stem cell-based intervention, for subacute spinal cord injury.

Not only that, but it is the first such therapy to look into treating this kind of injury, that has ever received government approval for sale to patients.

However there are concerns by those who work in the field, but arent working on this particular project, that the evidence to support the suggestion that the treatment works, is insufficient. They state that the approval for the research was based on a small, poorly designed clinical trial.

Like the majority of scientific breakthroughs that have gone before, there will always be naysayers we used to think the world was flat and the sun orbited Earth, that the body was composed of four humours and an imbalance in those made us sick.

Those theories were disproved, and look how far weve come since then. Now imagine if we could make a paralysed person walk again. It will happen. But for now, lets celebrate and support this team for trying.

Because whilst there have been multiple attempts to develop stem cell transplantation approaches with the aim to regenerate damaged spinal cords before, this multicentre team is planning the first that might actually work, and be ethical to boot.
