Induced pluripotent stem cells (iPSCs) can be differentiated into neuronal cells, providing valuable models for studying neurodevelopment and disease mechanisms. This process involves chemically defined culture conditions and small molecular inducers to guide differentiation. iPSC-derived neurons are instrumental in drug screening, toxicity assays, and regenerative medicine applications. Their ability to mimic human neural pathways enhances research into neurological disorders, offering insights into therapeutic strategies and personalized medicine.
