Very proud of our paper on "scrambling-by-hopping" LADs, which was just published: www.nature.com/articles/s41.... Congrats to Lise Dauban and the rest of the team – this was a real tour-de-force!

(1/14) I’m happy and proud to introduce: SpinePy – a framework to detect the "spine" of gastruloids and measure biological and physical signals in a local dynamic 3D coordinate system. www.biorxiv.org/content/10.1...

Ever wondered how to get a gastruloid to grow a head? The Bulut-Karslioğlu lab figured out that by growing different stem cell aggregates in high and low oxygen and later assembling them, you can get gastruloids with a fully formed neural tube. Check out our "In preprints": doi.org/10.1242/dev....

We are searching for an enthusiastic scientist to join our team and establish annual killifish as a model system for early developmental biology and biophysics! @embl.org @embldbunit.bsky.social Apply here: embl.wd103.myworkdayjobs.com/EMBL/job/Hei... Please re-post 🙏

New preprint with @gfudenberg.bsky.social We find the rate of cohesin loop extrusion in cells is set by NIPBL dosage and tunes many aspects of chromosome folding. This provides a molecular basis for NIPBL haploinsufficiency in humans. 🧵👇 www.biorxiv.org/content/10.1...

The Vlaming lab is expanding! If you are or know a good prospective PhD student, excited about studying transcription, please (suggest them to) apply here: www.uu.nl/en/organisat... My biased opinion: exciting topic, super nice colleagues, and great research environment in a lovely city.

Two new preprints from the @arjunraj.bsky.social‬ on #gastruloids. Both excellent. Exploring the relationship between macroscopic reproducibility v microscopic heterogeneity. Stunning experiments and much to think about biorxiv.org/content/earl... biorxiv.org/content/earl...

Please pread the word. We have just launched the Hubrecht International PhD Program (HIPP). Are you looking for a PhD position in molecular and developmental biology or related subject in an international, very supportive and collaborative environment? Then apply to the HIPP!! 👇

Excellent work supporting #modularity of the mammalian #embryo, a role for #hypoxia & how development exploits these features. It shows what we can learn from assemblies of #gastruloids @ spatio-temporal coordination of the modules in AP organization. Putting modules together, extremely informative

Fantastic work from @bulutkarslioglu.bsky.social group. we r happy to contribute on the role of hypoxia in proper gastrulation ex utero as originally noted in Aguilera-Castrejon et al. Nature 2021 for robust gastrulation. Now this is shown to be important for taking gastruloids to the next level.

⚠️ I am really excited to share the work of Anastasios Balaskas, an excellent PhD candidate in the lab, with the wider world. Tasos made a significant advance: generating a stem cell-based embryo model that contains both posterior and anterior neural tissues of the late-stage gastrulating embryo.

📢 Fresh off the press and featuring new exciting experiments! 🧪 We show how glycolytic activity instructs germ layer proportions through regulation of Nodal and Wnt signaling - happy to finally share this 😊 doi.org/10.1016/j.st... B2B with @jesseveenvliet.bsky.social lab: doi.org/10.1016/j.st... 🤩

🚨Just one week left to apply! Join our team @imbavienna.bsky.social!

Thank you! A special thanks to the organizers for putting this fantastic meeting together @moritzbauer.bsky.social @bracciolilab.bsky.social Hendrik Marks, Susana Chuva de Sousa, Lopes and Niels Geijsen. And to Wilke Meijer and Suzan Stello for working together on this exciting project!!

Well done @virginiar-andra.bsky.social from our lab for being awarded the Best Poster Prize at the International Dutch Embryo Model Meeting today for our work on “Spatiotemporally resolved omics reveals dynamic antagonistic gradients” in embryo segmentation. Congratulations!

Very happy to share that our paper on stem cell culture conditions is now out! doi.org/10.1371/jour... We found that modulating mESC culture conditions influences gastruloid elongation and lineage specification, and helps with making the protocol more reproducible in our hands! more below 🧵⬇️ [1/7]

And to finish a hat-trick of #gastruloid papers @bracciolilab.bsky.social on the influence of epigenetics on lineage decisions shorturl.at/aA6yy

🚨 Paper Alert 🚨 I'm incredibly proud and excited to announce that our latest research on the chromatin regulatory profile of gastruloids has been published in @DevCell! 🎉 Check out the full paper here: www.cell.com/developmenta... @dewitlab.bsky.social , @bracciolilab.bsky.social 🙌 🧵👇

Fantastic news!

Amidst these troubling times, I have some positive personal news to share: I will be joining @imbavienna.bsky.social as a new group leader this fall! 🎉 I am excited for fun projects, surprising discoveries, and great discussions within the fantastic science community @vbcscitraining.bsky.social

*Tenured full Professorship in Genetics and Molecular Cell Biology* at the University Of Cologne, Germany It's an opportunity to rebuild the place that used to be home to luminaries including Benno Müller-Hill, Max Delbruck, Campos-Ortega, Diethard Tautz Maria Leptin, Thomas Langer

"Genes are... the easy part" @philipcball.bsky.social argues biologists need to embrace complexity from the start, rather than beginning with oversimplified "one gene, one trait" models +1 www.cell.com/cell-systems...

🧫Looking for a PhD to start Autumn 2025? We're recruiting! 🧪 The project will focus on using #embryomodels to explore #development & could cover a range of specific questions. Please RT! 🙏 Apply via the portal, and get more details here: www.crick.ac.uk/careers-stud...
