Transplantation of neuronal stem cells successful
Researchers from Stanford University in California have successfully implanted neuronal stem cells grown from skin cells of Parkinson’s patients into animals’ brains, where they accreted, created networks over large areas and developed normal neuronal activity.
These observations in living organisms were possible because the stem cells were made light-sensitive by genetic alterations. Using various light impulses, the networks and activities could then be observed using magnetic resonance tomography.
