UTS researchers are experimenting with spinal cord tissue.

It all started at a symposium five years ago. Catherine Gorrie, an expert in spinal cord injury, was listening to a presentation about the differences between the developing brains of children and the mature ones of adults when she had an aah-haa moment.

I began to wonder if there is something in the spines of children that could be manipulated for repair, says Dr Gorrie, a neuroscientist at the University of Technology, Sydney (UTS). It made sense. Dr Gorrie already knew that the more adaptable, or plastic, spinal cords of infants responded more efficiently to injury than did those of adults.

If she could tease out the factors that encouraged generic cells, so-called stem cells, in the spines of newborns to become new nerve cells, neurones, Dr Gorrie reasoned that it should be possible to mimic the process and help repair spinal cord injuries in people of all ages. That would be incredibly important because, to date, there is no cure for spinal cord injury and no proven drug treatment.

The most effective treatments available involve the surgical stabilisation of the spinal column and extensive physical therapy to provide some functional improvement, Dr Gorrie says. There is nothing else.

In Australia, about 10,000 people live with spinal cord injury and 300-400 new cases emerge every year. Most injuries are a result of car accidents, sporting activities or severe falls.

Childhood spinal cord injury is frequently the result of tumours that compress the spine, crushing neurones which transmit signals to and from the brain.

As the notion of exploiting the biomechanical properties of infant spinal cords took shape in her mind, Dr Gorrie pulled together a team of UTS researchers: Dr Matt Padula, Dr Hui Chen and doctoral students Thomas Cawsey and Yilin Mao.
