A PhD student has developed a new technique that could revolutionize stem cell treatment for Parkinson’s disease and spinal cord injury. He has used existing polymer-based biodegradable fibers, 100 times smaller than a human hair, and re-engineered them to create a unique 3-D scaffold that could potentially allow stem cells to repair damaged nerves in the human body more quickly and effectively. A combined process of electro-spinning and chemical treatment was used to customize the fiber structure, which can then be located within the body.
