This study presents a novel microfluidic device for culturing neurons and testing drug effects. The micro-compartmented culture system (mu-CCS) allows targeted drug application to specific neuron parts, enabling advanced neurotoxicity studies.

Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Drug Discovery

Background:

  • Studying drug effects on neurons requires precise control over exposure.
  • Conventional methods lack the ability to selectively treat neuronal compartments.

Purpose of the Study:

  • To develop and validate a microfluidic system for targeted drug delivery to cultured neurons.
  • To enable selective biochemical treatment of neuronal segments or populations.

Main Methods:

  • Fabrication of a microfluidic system with isolated compartments.
  • Culturing dorsal root ganglion (DRG) neurons within the microfluidic device.
  • Utilizing micropatterned collagen films for controlled axonal guidance.
  • Demonstrating fluid isolation between compartments while allowing axonal extension.
