We've just updated our manuscript to a more 'publishable' version! biorxiv.org/content/10.110… New details about the role of Wnt in suppressing neural differentiation and fostering a posterior epiblast state, and the temporal effect of Nodal signalling in driving mesendodermal fates

In which we discuss the homologies between amphibian and mammalian #organizers from the perspective of #gastruloids with special relevance to recently described A and C gastruloids as containing Spemann/Mangold and Trunk/Tail organizers sciencedirect.com/science/articl…

“Lineage recording in monoclonal gastruloids reveals heritable modes of early development” Great work ⁦Jay Shendure⁩ ⁦Junhong Choi⁩ ⁦Samuel Gabriel Regalado⁩ !!!! biorxiv.org/content/10.110…

We are hiring #postdocs and #phd students in the areas of #devbio #cellbio #Bioinformatics #mathematics #modeling. This is the full add with details: euraxess.de/jobs/346670 This our lab homepage: uniklinik-freiburg.de/walentek-en.ht…

Next Thursday (June 5th), please join us for the next Western VGZT 🌙 Our speakers are: 👉 Luke Simpson “Gastruloids reveal the dynamics of interspecies development and chimerism” 👉Thierry Lepage “Maternal factors shaping the spatial expression of nodal”

Big news! "researchers will be eligible to apply for a Starting Grant immediately after successfully defending their PhD, and at any time within the following ten-year period." #ERC #ERCstarting erc.europa.eu/news-events/ne…

We have multiple open positions in #cellbio #devbio #singlecell #microbiome #genomics in the lab and posted it on The Node thenode.biologists.com/jobs/walentek-… #xenopus #mouse #mucociliary

The modularity of the mammalian #embryo in display. Controlled assembly of classic #gastruloids and uncommitted precursors in #hypoxia, patterns the AP axis biorxiv.org/content/10.110… Beautiful from Aydan Bulut-Karslioglu group. Building to learn! The embryo is a modular structure.

1/ 📢 Some decisions change everything. Continuing your research is one of them. Are you ready to boost your STEM career in Spain or Portugal with a postdoctoral Junior Leader #fellowships? 🗓️ Apply before 25/09, 2025. 👇 🔗 bit.ly/4lidtkl

[0/8] Super stoked to share our work with Arjun Raj on tissue organization in the gastruloid. We use lineage tracing and spatial transcriptomics to show that diversity among stem cell clones promotes, rather than hinders, gastruloid development: biorxiv.org/content/10.110…

🚨New paper out!🚨 🔬 CRISPRa screening during mesodermal differentiation identifies 7 key genes with HSC induction potential. 🧬 A 7-gene cocktail drives multilineage repopulation and self-renewal from mouse ESCs. 📄 Don’t miss it! doi.org/10.1182/blood.…

Today is the FINALE 🌟 Don’t you forget to attend today’s session featuring our keynote speaker Josh Brickman

1/ 👨‍🔬 Meet the postdoctoral Junior Leader #laCaixaFoundFellows Joshua Frenster and team! At UPF Barcelona, he is exploring how cells in embryos “compete” to make sure only the fittest ones build the body. They use 3D stem cell models to watch this process in action.

Joshua Frenster UPF Barcelona Fundación ”la Caixa” Fundação "la Caixa" 2/ “The fellowship let me lead my own research and explore original directions. It also helped me spark new connections across fields. Having a great mentor, Prof. Alfonso Martínez Arias, was crucial in supporting my growth in the lab.”  💬 Joshua Frenster UPF Barcelona.

Excited to co-organize the Keystone Symposium “Stem Cell Models in Embryology” with Jianping Fu and Miki Ebisuya! Join us Feb 17–20, 2026 at Asilomar to explore cutting-edge advances in stem cell–derived embryo models. Spread the word! keysym.us/KSEmbryology26 #KSEmbryology26

Excited to share our new study on an integrated human SCBEM! Congratulations to Seiya and Leijie! While the model isn’t perfect, we hope it serves as a valuable tool to help tackle some of the key unanswered questions in early human development. cell.com/cell-stem-cell…

With the group that came together upf.edu in #Barcelona, celebrating 5 years of exploring, dreaming and discovering. Grateful #NotInTheGenes #CellsRUs
