The mouse blastocyst is a key model for understanding early development. New tools help unravel how cell lineages form and make fate decisions in a self-organizing context.

Area of Science:

  • Developmental biology
  • Genetics
  • Molecular biology

Background:

  • The preimplantation mouse embryo model has evolved over 50 years.
  • Understanding of blastocyst molecular pathways has improved.
  • Fundamental questions of lineage commitment persist.

Purpose of the Study:

  • To explore how organized cell fate decisions are made.
  • To investigate self-organizing developmental contexts.
  • To leverage new technologies in studying early mammalian development.

Main Methods:

  • Genome manipulation techniques.
  • In vivo imaging.
  • Single-cell analysis.
