A pendulum of induction between the epiblast and extra-embryonic endoderm supports post-implantation progression

Vrij et al. aim to elucidate the principles of epiblast and extraembryonic endoderm co-development in mice. SORT-seq and immunofluorescence microscopy analysis indicate a process of lineage bifurcation and the two layers sequentially inducing developmental progression in each other.
