New 3D-printed tools enable high-resolution live imaging of zebrafish germ granules. This method facilitates detailed studies of ribonucleoprotein (RNP) granule dynamics during early development.

Area of Science:

  • Developmental Biology
  • Cell Biology
  • Microscopy

Background:

  • Ribonucleoprotein (RNP) complexes form germ granules during early zebrafish development.
  • Germ granule dynamics are crucial but not well understood, potentially involving the cytoskeleton.

Purpose of the Study:

  • To develop efficient mounting strategies for high-resolution live imaging of early zebrafish embryos.
  • To enable detailed studies of germ granule dynamics using advanced microscopy techniques.

Main Methods:

  • Utilized 3D-printed tools to create multiplexed wells on agarose-coated sample holders.
  • Developed methods for direct water-dipping lens access to mounted embryos for inverted and upright microscopes.
  • Integrated new transgenic reporter lines for germ granule visualization.

Main Results:

  • Achieved efficient mounting of early zebrafish embryos (less than one day post-fertilization) for live imaging.
  • Enabled obstruction-free, high-resolution imaging on spinning disk confocal, lattice light-sheet, and diSPIM microscopes.
  • Facilitated detailed observation of germ granule dynamics at various developmental stages.

Conclusions:

  • The presented 3D-printed tools and mounting strategies significantly improve the throughput and resolution of live imaging for early zebrafish embryos.
  • These advancements provide a powerful platform for investigating the complex dynamics of germ granules and their role in development.
