Unraveling Enteroendocrine Cell Lineage Dynamics during Intestinal Development

Strategic Insights -

Research conducted by a team of scientists at the University of Strasbourg has shed new light on the processes that determine the subtype specification of enteroendocrine cells (EECs) during development. Using mouse embryos and human pluripotent stem cell-derived intestinal organoid models, the researchers identified the majority of EECs as being specified during development through similar differentiation trajectories to those observed in the adult intestine. Their findings suggest that EEC subtype specification occurs independently of fully organized crypt-villus structures and stimulation by diet or microbiota.

Key Takeaways:

  • The research team used mouse embryos and human pluripotent stem cell-derived intestinal organoid models to characterize EEC lineages and dynamics during development.
  • The results showed that the majority of EECs are specified during development through similar differentiation trajectories to those observed in the adult intestine.
  • EEC subtype specification occurs independently of fully organized crypt-villus structures and stimulation by diet or microbiota.
  • The emergence of certain EEC subtypes depends on tissue maturation.
  • The researchers identified new candidates controlling EEC differentiation in the developing human gut using their integrative approach.
  • Sara Jimenez, Aline Meunier, Rishabh Kapoor, Valerie Schreiber, Colette Giethlen, Sabitri Ghimire, Maxime M. Mahe, Nacho Molina, Adele De Arcangelis, and Gerard Gradwohl were co-authors on the research.
