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.
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.
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.
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.
Single cell RNA sequencing reveals that mouse embryonic stem cells can be differentiated into the same terminal motor neuron state via distinct differentiation paths, one of which includes a surprising intermediate state not found in embryos.
