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 5

Depicts the balance between degeneration due to illness and the neuroregenerative reserve present in the brain. The schematic diagram illustrates that higher the degeneration higher the illness and more the regeneration required. Exogenous supply of stem cells midway between these two stages (i.e., 50%) would aid in improving the quality of life and reducing the disability due to disease.
