Main Methods:

  • Developed a microfluidic platform utilizing passive hydrodynamics for on-chip worm cultures.
  • Achieved synchronized embryo populations and immobilization in microarrays for imaging.
  • Enabled long-term, high-resolution optical imaging of complete embryogenesis.

Main Results:

  • Successfully implemented an automated system for C. elegans embryo culture and imaging.
  • Investigated morphogenesis and mitochondrial biogenesis throughout embryonic development.
  • Elucidated the role of UPRmt in C. elegans embryogenesis.

Conclusions:

  • The developed microfluidic platform meets the requirements for studying real-time embryonic dynamics.
