Our take on a really interesting new study by the Franz lab at UCL, a version of epithelial polarity where you would not expect it! Read our Spotlight and the original paper!
Spotlight: Ball and Röper @pdncambridge.bsky.social discuss recent findings by Almasoud, Franz et al. (rupress.org/jcb/article/...) describing how apical–basal polarity regulates cell–cell adhesion in the #Drosophila fat body. rupress.org/jcb/article/...

Very cool story!
⚡👩‍🔬Electrical signals are key for promoting organ regenerative growth, a new study!

Out now in Science Advances, from the Mateus group @ritamateus.bsky.social at PoL and @mpi-cbg.de along with the lab of Frank Jülicher @mpipks.bsky.social

Check out the tour de force by @jalehtimaki.bsky.social in its final form: www.sciencedirect.com/science/arti... . An elegant combination of transcriptomics, F0 screens and high end imaging unravels the cues that guide cells (here retinal horizontal cells) in an increasingly crowded tissue. #proudPI
Spatiotemporal coordination of Slit-Robo repulsion and neurturin-Gfrα attraction guides multipolar migration during retinal lamination
Multipolar migration is a conserved neuronal migration mode in the developing brain, enabling emerging neurons to navigate in crowded environments and…

Cool new paper from the Munro lab!
The small #GTPase Rab1 is a master regulator of #Golgi traffic and #autophagy. van Vliet, Munro et al. @mrclmb.bsky.social performed a proteomic screen to identify novel Rab1 effectors, including a #dynein motor adaptor and cargo receptors for autophagy. rupress.org/jcb/article/...

So cool! How any of these processes can happen with such precision and speed in a madly dense cytoplasm never stops amazing me!
Today, our animation synthesizing decades of research on actin-mediated endocytosis in budding yeast was published:

The result of a fantastic Iwasa-Drubin lab collaboration.

Very sad news indeed…
John Gurdon, former Group Leader and Head of @cellbiol-mrclmb.bsky.social has died.
Despite calling himself a "total non-intellectual” his work to reprogramme somatic cells to pluripotent stem cells transformed the field of developmental biology.

Supracellular actomyosin assemblies: master coordinators of development

In this Review, Katja Röper @katjaroeper.bsky.social discusses supracellular actomyosin structures, tissues where they function, their known roles as well as potential properties

Supracellular control and coordination of tissue morphogenesis, through supracellular actomyosin assemblies, that is what my lab @cellbiol-mrclmb.bsky.social @pdncambridge.bsky.social and I like to dig into at the moment! Fascinating and beautiful! journals.biologists.com/dev/article/...

We cannot provide invoices at present but are working on a system to do so in the near future. However, you will receive a receipt for your tax-deductible donation. Large teams of people work to keep FlyBase going, and the need is great, so please donate generously.

Flybase is free to use but not free to make. It takes large teams of people and millions of dollars a year to create the knowledgebas and tools for fly research. Please donate generously.
FlyBase needs your help! We ask that European labs continue to contribute to Cambridge, UK FlyBase, whereas US and other non-European labs can contribute to US FlyBase. For more information and how to donate: wiki.flybase.org/wiki/FlyBase...

For something as classic as the Spemann-Mangold organizer first discovered in amphibians, the existence of such an organiser in mammals remains elusive. In this thought provoking review by Kate Mcdole et al, they discuss the evidence for and against such organiser in mouse.
