Bilateral Transplantation of Allogenic Adult Human Bone Marrow-Derived Mesenchymal Stem Cells into the Subventricular Zone of Parkinson’s Disease: A Pilot Clinical Study

Figure 3

Illustrates the improvement in UPDRS scores for PD patients before and after stem cell transplantation. The graph highlights the fact that the patients treated early at the onset of the disease (5 years) have shown significantly better improvement which correlates clinically. The patients that were treated between 10–15 years after the diagnosis of PD did not show any significant improvement.
