Area of Science:

  • Neuroscience
  • Developmental Biology
  • Biotechnology

Background:

  • Axon fascicles are crucial for nervous system structure and function.
  • Disruptions in axon fascicles are linked to developmental and neurodegenerative diseases.
  • Existing in vitro models lack the robustness for studying axon fascicle formation and dysfunction.

Purpose of the Study:

  • To develop a rapid, 3D in vitro model for studying axon fascicles.
  • To create motor nerve organoids (MNOs) from human induced pluripotent stem cells (iPSCs).
  • To establish a platform for investigating axon fascicle development and disease mechanisms.

Main Methods:

  • Fabrication of microfluidic tissue culture chips.
  • Generation of motor neuron spheroids (MNS) from human iPSCs.
  • Culturing MNS in microfluidic chips to promote spontaneous axon outgrowth and fascicle formation within microchannels.

Main Results:

  • Successful generation of motor nerve organoids (MNOs) with bundled axons.
  • MNOs provide a 3D in vitro system for studying axon fascicles.
  • The protocol enables downstream analyses including morphological, biochemical, calcium imaging, and electrophysiological recordings.

Conclusions:

  • The developed MNO protocol offers a robust 3D model for axon fascicle research.
  • This model facilitates drug testing, screening, and mechanistic studies of neurological disorders.
  • MNOs advance the understanding of axon development and neurodegenerative diseases.
