Headline: "Scientists discover emperor penguin colony in Antarctica using satellite images"

Yesterday it was cows using tools, today its penguins using satellite imagery.

Please check out our job post @biologists.bsky.social!

We are recruiting a Postdoc Scientist to develop cutting-edge tools and techniques for bioengineering human lymphatic networks, as part of an interdisciplinary collaboration with the group of Prof Dame Molly Stevens!

Today’s #ScientificImage — “Where Vessels Begin,” comes from @degrainger.bsky.social, a postdoctoral researcher in IDRM's Stone group.

💬"We are working to understand how blood and lymphatic vessels form during embryonic development and how organ-specific characteristics of these vessels arise."

Institute of Developmental and Regenerative Medicine (IDRM)'s Mo Space Movember, the month formerly known as November, is a moustache growing charity event held during November each year that raises funds and awareness for men's health.

Our Institute for Desperately Regrowing Moustaches @idrm.ox.ac.uk is raising money for men’s mental health, suicide prevention, and prostate and testicular cancer awareness by growing moustaches. Please donate on our Movember page if you're able!

Hierarchical lineage architecture of human and avian spinal cord revealed by single-cell genomic barcoding The formation of neural circuits depends on the precise spatial and temporal organisation of neuronal populations during development. In the vertebrate spinal cord, progenitors are patterned into mole...

Thrilled to share my main postdoc work with @jamesbriscoe.bsky.social

We used genomic barcoding + scRNAseq in chick & human embryos to reveal a lineage architecture that reshapes how we understand neural tube development & cell fate decisions

Oxidative phosphorylation is required for cardiomyocyte re-differentiation and long-term fish heart regeneration Nature Cardiovascular Research - Lekkos et al. show that a metabolic switch toward oxidative phosphorylation is required for cardiomyocyte re-differentiation and heart regeneration after injury in...

Do zebrafish regenerate their hearts equally? In our new paper at the @tillymommersteeg.bsky.social lab we uncovered variations in the regenerative response of 7 wt zebrafish strains leading us to identify a critical role of oxidative phosphorylation in long-term heart regeneration.

Genetic lineage tracing identifies intermediate mesoderm as a novel contributor to mammalian kidney lymphatics The lymphatic vasculature is essential for fluid homeostasis, immune regulation and possesses diverse organ-specific functions.

Excited to share our new collaborative preprint between @uclnews.bsky.social and @sickkidsto.bsky.social 🥳

We found that kidney lymphatic vessels, an emerging target in kidney diseases, partly arises from the same group of cells that give rise to the kidney

We already have some amazing contributions from early career researchers from the UK, Switzerland and US. We would love to see contributions from other countries as well! If you can't travel to the conference remember you can always participate online.

#onlywithHCR: @degrainger.bsky.social, @oliverastone.bsky.social, and their team reveal that lymphatic endothelial cells arise from specialized progenitors. #HCRimaging helped them to visualize endothelial progenitors in whole-mount mouse embryos.
