In this episode, I chat with Professor James St John who is head of the Clem Jones Centre for neurobiology and stem cell research. His team have developed a world leading stem cell treatment that is hoped to cure or treat spinal cord injuries and in collaboration with others, will be conducting a world first human trial using these cells. I chat with James about what the trial involves, how these nasal cells were discovered to be effective in spinal-cord injury treatment, the science behind how they will help people with spinal injuries and how he came to be head of this research.
