Betterhumans comments on recent important research that details an efficient method for prompting stem cells to change into motor neurons. A method of producing motor neurons is an essential part of any regenerative therapy that will address spinal injuries and degenerative conditions of aging like Parkinson's. It is good to see the pieces of the puzzle coming together, one by one. Scientific understanding is leading to results, and results lead to therapies that will enable us all to lead longer, healthier lives. Support our researchers!
