Implementation Considerations

• Requires expertise in neural cell culture, microfluidic device handling, and electrical stimulation setup.
• Depends on instrumentation including laser scribers, thermal bonders, ITO heaters, XYZ stages, and function generators.
• Necessitates cross-team standardization of coating protocols, medium exchange, and electrical pulse parameters.
• Involves adaptation considerations for different NPC sources and extracellular matrix coatings beyond poly-L-lysine.
• Includes practical limitations such as bubble formation in channels and the need for manual flushing to maintain flow integrity.
