Area of Science:

  • Developmental Biology
  • Cell Biology
  • Genetics

Background:

  • Gastrulation is a fundamental process in vertebrate development.
  • It involves precise cell movements to establish the three primary germ layers: ectoderm, mesoderm, and endoderm.
  • Studying gastrulation offers insights into fundamental cell migration mechanisms.

Purpose of the Study:

  • To elucidate the cellular and molecular mechanisms driving cell movements during zebrafish gastrulation.
  • To provide a model system for in vivo cell migration studies.
  • To compare findings with other model systems to identify conserved mechanisms of cell migration.

Main Methods:

  • Observation of cellular movements during zebrafish gastrulation.
  • Analysis of molecular pathways involved in cell migration.
