Gastrulation is a key developmental process during which embryonic pluripotent stem cells of the blastula reorganize into lineage-committed precursor cells to form the gastrula. Making a commitment: cell lineage allocation and axis patterning in the early mouse embryo. We combined stem cells to create embryo models that establish three compartmentsto my knowledge, for the very first timeat postimplantation stages. 163, 103617 (2020).

Comparison with mouse gastrula transcriptomes revealed many commonalities between the human and mouse but also several key differences, particularly in FGF signaling, that we validated experimentally.
