Two years since the 1st submission, our work on limb heterochrony is finally out! 🎉🎊 @cellcellpress.bsky.social Delayed hindlimb dev vs forelimb is a widely conserved trait in mammals. We show that maternal O2 regulates this phenotype 👉🏻 shorturl.at/MGrwl

Shifts in embryonic oxygen levels cue heterochrony in limb initiation
Mammalian embryos see a substantial increase in available oxygen once the placenta forms. This increase in oxygen exposure serves as a trigger for initiating the development of the hindlimb, thus cont...

🧬 Preprint! 🧵 Our goal is to genetically manipulate every embryonic germ layer to enable high throughput in vivo studies. We previously showed mouse ectoderm can be targeted by amniotic injection, enabling cell-specific manipulation, lineage tracing, and knockouts. But how to reach mesoderm?
Schematic of method developed and application. At embryonic day 7.5, a lentiviral library carrying unique 30-nucleotide barcodes and a fluorescent reporter is injected into the mouse exocoelomic cavity. An E8 embryo cross-section shows that this cavity is continuous with the intraembryonic coelomic cavity, allowing the virus to reach and barcode mesodermal progenitors, including lateral plate and paraxial mesoderm.

Chromatin ist nicht unbeweglich. Es handelt sich um ein hochdynamisches Material, dessen 3D-Struktur zentrale genomische Prozesse – von der Transkription bis zur DNA-Reparatur – steuert. Doch wie verhält sich Chromatin als Material – als Flüssigkeit, Feststoff oder viskoelastisches Gel –, um diese Funktionen in lebenden Zellen auszuführen? Ohne eine Antwort auf diese Frage können wir nicht vollständig verstehen, wie Chromatin bei Krankheiten gestört wird.
