Using fluorescence live imaging and an in vitro implantation model, we show that human embryo attachment begins with direct cell fusion via syncytin-2–MFSD2A interaction. With @hansclevers.bsky.social. Great work by @tnoordzij.bsky.social & @martinacelotti.bsky.social www.biorxiv.org/content/10.6...

Lovely little pre-Christmas present to see this out @natcellbio.nature.com! Some 🔥 new results in here since the biorvix incl (1) a new RARE-GFP reporter ✳️🙌, (2) additional NMP quantification 🔢, (3) no neural tube patterning on RA inhibition 🙅 etc. Enjoy! 😍 www.nature.com/articles/s41...

Good to see the peer reviewed version of this published A chemo-optogenetic system for spatiotemporal control of gene expression We use it to: - Reconstruct SHH mediated neural tube patterning in vitro - Measure extracellular half-life of Shh www.cell.com/developmenta...

A really thoughtful and interesting review by @cellysally.bsky.social on how cells synchronise with their neighbours to build tissues.

SY-Stem 2026 is here! The symposium focusing on the next generation of stem cell researchers returns to the Vienna BioCenter from 11–13 March 2026. Register online: sy-stem.org

Meeting schedule now online for @bsdb.bsky.social 2026 spring meeting: Molecules to Morphogenesis! ***Abstracts due in by January 16*** Join the outstanding line up! Submit your abstract for a short talk, flash talk, or poster presentation: 👇👇👇 bsdb.org/meetings/

Join us for the second seminar in the online Metabolism in Development and Physiology series next Thursday. Two exciting talks lined up from different career stages.

Incredibly excited to receive an ERC Consolidator Grant. This recognition means a lot for what we’ve built so far and for what’s ahead. Thank you to all collaborators and supporters. Looking forward to getting this project going!

📢 a cool group, leader, and science! Great research opportunity in Barcelona

Wow, this is a very impressive embryo model. "What sets the model described in this study apart from other embryo models is its ability to continuously mimic primate development from pre-implantation through to late gastrulation." (Nice, @amartinezarias.bsky.social!) www.nature.com/articles/d41...

Great to see this published: Fitting dynamical landscape models to single-cell data, creating interpretable maps of cell decision making & developmental logic Applied to neural tube patterning, we show how morphogen signals reshape landscapes and drive fate decisions www.pnas.org/doi/10.1073/...

📢Internships on cellular nematics! 🔬Come for the pretty images, stay for the cool physics: each project combines in vitro experiments with advanced microscopy and image analysis. 📧Feel free to DM or email me with any questions.

Good to see the peer reviewed version of this in print The cis-regulatory logic integrating spatial and temporal patterning in the vertebrate neural tube A global temporal chromatin program operates across the vertebrate nervous system to control neural cell diversity www.cell.com/developmenta...

I tried out the Mamdani slogan generator and this is what I came up with 🤷🏼‍♀️ homes.luddy.indiana.edu/ccshan/for/f...

How can we organize current theoretical approaches for developmental biology - from information to dynamical systems & GRNs - into a common framework? We propose to think along Marr's 3 levels: computational problem, algorithm, implementation Check out our review: arxiv.org/abs/2510.24536

Very happy to share our latest work extending iterative immunofluorescence to in toto imaging of early zebrafish embryos (3D-4i), integrated with a 3D-dedicated image analysis pipeline! 🐟🔬📊 Huge kudos to Max Hess for this PhD milestone! 💪 @lucaspelkmans.bsky.social shorturl.at/cO0u7 Let's zoom in!

Really excited to present the results of a fantastic collaboration with Jesse Veenvliet @jesseveenvliet.bsky.social @mpi-cbg.de @poldresden.bsky.social 🤩 We find a unique mechanism for body axis elongation in mammals, different from other vertebrate species ➡️ www.biorxiv.org/content/10.1...

Launching new online international seminar series at the interphase of metabolism, developmental biology and cell biology

Not the submission process, not reviewer #2, not the editor. Writing the abstract of the paper is often a far greater challenge. And there’s one simple reason for that: most people have a hard time figuring out what’s important for the reader. I ‘ll be sharing tips in next posts - stay tuned!

another fascinating collaboration with the Turco lab @fmiscience.bsky.social www.biorxiv.org/content/10.1...

How is developmental speed regulated ? 🪰 Happy to share my PhD story from Schweisguth Lab @devstempasteur.bsky.social. Here we show that cellular NAD+ availability and redox constrain developmental speed in the fly eye. www.biorxiv.org/content/10.1... A big thanks to everyone involved!

We have developed a new workflow to map whole human organs at single-cell resolution, while integrating spatial transcriptomics, proteomics, and metabolomics. We applied this workflow to map precancerous lesions of the fallopian tubes. More here: www.biorxiv.org/content/10.1...

Core achievement unlocked!! Congrats to Fabrizio amd all authors!!
