By enabling the reconstruction of the nigrostriatal pathway through guided axon growth, nano-pulling could enhance the efficacy of cell transplantation strategies and help restore functional connectivity in the brain. To test this system, the research team first constructed an organotypic brain slice model that mimics early-stage PD by co-culturing brain sections containing SN and ST. Transplanted cells exhibited increased branching, greater synaptic vesicle formation, and improved microtubule stabilitykey indicators of neuronal maturation and functional integration. Mechanical forces guide axon growth through the nigrostriatal pathway in an organotypic model. Parkinson’s disease is characterized by the progressive degeneration of dopaminergic neurons in the substantia nigra (SN), which project to the striatum (ST) via the nigrostriatal pathway. They transplanted human neuroepithelial stem (NES) cells, preloaded with MNPs, into the SN region. The loss of these connections leads to dopamine deficiency and the onset of motor symptoms.
