Technologies for Live Imaging of Enteric Neural Crest-Derived Cells

Area of Science:

• Developmental Biology
• Neuroscience
• Gastroenterology

Background:

• Enteric neural crest cells (ENCCs) are vital for forming the enteric nervous system.
• Understanding ENCC behavior is crucial for addressing neurocristopathies affecting the gut.

Purpose of the Study:

• To develop and validate a time-lapse imaging method for observing ENCCs in embryonic gut explants.
• To enable detailed behavioral analysis of ENCCs in a 3D context.

Main Methods:

• Dissection and mounting of embryonic mouse gut explants on filter supports.
• Culturing explants in a 3D-retaining configuration within a confocal microscope environmental chamber.
• Acquiring time-lapse confocal z-series images of fluorescently labeled ENCCs at regular intervals (3-10 minutes).

Main Results:

• Successfully visualized dynamic ENCC behavior within the explant's native 3D structure.
• The imaging protocol captured cellular migration and network formation over time.
• Projected z-series provided comprehensive spatial and temporal data.

Conclusions:

• Time-lapse confocal microscopy of fluorescently labeled embryonic gut explants is an effective method for studying ENCC behavior.
• This technique provides valuable insights into enteric nervous system development.
• The method facilitates the analysis of cellular dynamics critical for gut innervation.
