At gastrulation, mesoderm arises as a migratory germ layer that will participate to both foetal and placental development through region-dependant adaptation of cytoskeleton composition, cell shape and migration mode.
Lineage specification and commitment are synchronized in the developing trophectoderm lineage of the mouse embryo, but are asynchronous events in the maturing inner cell mass, revealing a window of plasticity in this lineage.
The Notch signaling pathway drives transitions in differentiation capacities during the gradual loss of potency that occurs in the preimplantation mouse embryo before the onset of the first lineage decisions.
Post-implantation epiblast maturation and patterning of anterior-posterior axis in mouse embryonic development are mediated by pluripotency transcription factor Zfp281 through transcriptional and epigenetic control of Nodal signaling.
The uniparental inheritance of mammalian mitochondria results from elimination of paternal mitochondria by a mitophagic process that requires the E3 ubiquitin ligases PARKIN and MUL1.
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.
Single embryo RNA-seq combined with mouse genetics provides a comprehensive view on the roles of Rlim and Xist for the regulation of X-linked gene expression during early mouse embryogenesis.
Primed Track is an image analysis tool that allows for computational correction of drifting specimen to enable accurate lineage tracing of mammalian pre-implantation development even for larger imaging time intervals.
The transcription factor GATA6 selects the embryonic vessels that will be reorganized into the major thoracic arteries by promoting local differentiation of vascular smooth muscle cells.
