Model Organism: Frogs

Why frogs?

Frog embryos have distinct advantages for the study of digestive organ development:
  • Transparency: The development of the digestive organs can be monitored in living embryos over time.
  • Morphogenesis: The complex elongation and rotation necessary to form the final anatomy of the amphibian GI tract are highly analogous to the events that occur in mammals.
  • Accessibility: Frog embryos develop rapidly , and are large enough to undergo microsurgery or microinjection.                               The coiling gut tube is visible in the living tadpole.
