This study presents the development of a Nervous System-on-Chip (NoC) using microfabrication techniques, focusing on the integration of human induced pluripotent stem cell (hiPSC)-derived neurons. We designed and fabricated NoCs based on microtunnel devices (MDs) with radial and linear configurations to facilitate the compartmentalized culture of cortical and enteric neural networks. Our findings demonstrate that these MDs allow axonal growth while restricting migration of somas and dendrites between compartments, thereby promoting the formation of organized neural networks. This creates a microfluidic platform capable of supporting the growth of different culture systems, which could potentially be combined to study interactions between the central and enteric nervous systems. The resulting neuronal networks exhibited viability, expression of key lineage markers, and synapse formation, highlighting the platform's potential for advanced nervous system modeling. MD-based NoC models provide an innovative microfluidic platform for studying the biology of human neural networks, with implications for the investigation of neurodegenerative diseases such as Parkinson's Disease and applications in pre-clinical research.
