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.
While photoreceptor and bipolar cells exhibit very similar cis-regulatory grammars, subtle differences in homeodomain motif enrichment represent a key distinction driving the divergence in their transcriptomes.
Satellite DNA mediates clustering of multiple chromosomes via formation of chromocenter to encapsulate the full complement of the genome into a single nucleus.
Regenerating neural progenitors of the Xenopus tropicalis tail prioritize differentiation to motor neuron types earlier than proliferation, a decision partly regulated by the transcription factors Pbx3 and Meis1.
A new system to genetically label and manipulate plasma cells in vivo in their microenvironment resolves current technical limitations and reveals tissue-specific homeostatic population turnover.
