Summary:
A combination of stem cells, growth factors and other treatments can heal damaged neural circuits, allowing partially paralyzed rats to walk. These findings represent a significant step forward in regenerative medicine, providing new treatment possibilities for Amyotrophic Lateral Sclerosis (ALS) and other neurodegenerative diseases, as well as some types of spinal-cord injury.
Researchers caution that the work is just a first step, and that human trials are likely several years away. Indeed, the findings highlight just how complex spinal injuries and neurodegenerative disorders are and how complicated successful treatments are likely to be.
Scientists say variations of the technique could ultimately have applications for a wide range of neurological disorders, including Parkinson's disease.
Commentary: Hopefully these growth factors will work effectively in humans to treat central nervous system injuries and disorders.
