Live imaging coupled with cell lineage tracing in chick and mouse embryos reveal that the cardiac regulatory gene Nkx2.5 is also transiently expressed in early extra-cardiac hemogenic angioblasts that migrate to the heart, yolk sac and dorsal aorta.

Finch embryos are laid at an earlier stage than other avian embryos and contain cells with similar properties to pluripotent embryonic stem cells from mice.

Fate-mapping, combined with gain- and loss-of-function approaches, reveal the role of BMP signalling in the spatio-temporal development of the tuberal hypothalamus, a critically important brain region.

A single-cell transcriptomic resource of the early chick epiblast from mid-gastrulation through neurulation highlighting emergence of the neural plate border territory, with emphasis on neural crest specification.

Chick optic fissure closure is a powerful new model system for epithelial fusion and has revealed Netrin-1 as a conserved and essential mediator of tissue fusion in multiple contexts.

Multiple levels of gene regulation in the TGFβ signaling pathway mediate the expression of Mmp13, establish species-specific domains of bone resorption, and likely generate evolutionary variation in jaw length.

Directed mechanical stresses can trigger active T1 events that lead to tissue elongation perpendicular to the main direction of tissue stress.

The vertebrate neural plate border is comprised of precursors that coexpress multiple lineage markers and small changes in their levels can bias border cell fate.

Neural crest cells differentiated from patient-derived cells with mutations in the chromatin remodeler CHD7 show defective delamination, migration and motility in vitro, and defective migration in chick embryos.

In higher vertebrates, the position of the embryonic axis (the location at which gastrulation starts) is determined by the transcription factor Pitx2, which suggests that the mechanisms of this process, and hence those that regulate twinning, are related to those that set up the left–right axis.
