🧬 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.

Astrocytes do so much more than any of us thought - they even communicate among specific brain regions across hemispheres! The journey to this paper spanned nearly a decade, but I'm most excited to see what everyone else does with the tools we've built. There's so much for all of us to explore!
