Since it's never too late, the Martinez Arias lab wishes you all a Happy New Year! 🎊

[Alfonso Martinez Arias @AMartinezArias]

THANK YOU for many years of friendship, support and for sharing your great Science. La Pedrera #Barcelona

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

What happens when you plate #gastruloids at different times on different substrates is that we learn about cells, pattern formation and gastrulation. Excellent experiments from G. Serrano and @BenSteventon2 raising interesting questions

Really interesting stuff. Good to see #gastruloids increasingly put good uses. Looks as if there might be insights here as to the well noted impact of the initial PSC state in cell fate choices and differentiation.

President of @ERC_Research @mleptin urge us to develope attractive academic career paths on the national level. Not everything can be solved at the EU level, prof. Letin says #Yerun10

Are you passionate about neuroscience and developmental biology? 🧠🐟
Join an exciting project on neural development in zebrafish with Gonzalo, an amazing and supportive mentor, can’t recommend him enough!

The newest version of our recent preprint is out now!

[André Dias @_andre_Dias_]

We've just updated our manuscript to a more 'publishable' version!

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

Just published a new edition of “Principles of Development’ from “Wolpert’s Principles of Development’ to honour his memory and the origin of this textbooks that aims at distilling the, sometimes elusive, principles underlying animal and plant development https://t.co/eNCTuQAHtj

We’re looking for PhD students to join the lab! 🧫🧑‍🔬
Curious about how metabolic processes shape patterning and morphogenesis? Enthusiastic about stem cell models for human development? - Then apply through the VBC PhD program! https://t.co/peCAFrZVem

‼️Deadline: April 15‼️

Perhaps the beginning of something.
#Gastruloid community, Barcelona 2025 after Marseille 2024 Nice to see human self organization at work in these challenging times. It was good to see US colleagues joining us and breathing european air! We appreciated their joining in.

[Martinez Arias lab @AMA_lab]

Being able to bring together part of the #gastruloid community in this special meeting was incredible. Thank you all for participating in this event, and keep up the great science!

[Martinez Arias lab @AMA_lab]

The 2025 Gastruloid Meeting in Barcelona has already come to an end, with fascinating closing remarks by @nmoris. Many thanks to all of you for joining us and sharing your research, it was a wonderful gathering!

[Martinez Arias lab @AMA_lab]

More fascinating talks today at the 2025 Gastruloid Meeting!

[Martinez Arias lab @AMA_lab]

Today we kicked off the first day of the 2025 Gastruloid Meeting in Barcelona with a talk by our invited speaker @da40cambs. Thanks to all the presenters and almost 100 attendees for great discussions! Looking forward to what comes tomorrow 🙌

[Kristina Stapornwongkul @KStapornwongkul]

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

[Martinez Arias lab @AMA_lab]

🚨New preprint alert!
Excited to share the latest work from our lab. In this study Ulla, Sara and colleagues investigated the role of size in #gastruloid AP patterning, tissue mechanics and elongation, with potential implications for mouse development!

🚨 New preprint alert! In the latest work from our lab,
@_andre_Dias_ and colleagues dissected the role of a Wnt/Nodal antagonistic signalling module in patterning the emerging mammalian body plan, using #gastruloids as a model. Cool work!

[Martinez Arias lab @AMA_lab]

🚨 A new preprint from our lab is out now! In this study, @JoshiFrenster and colleagues show that #gastruloids are a powerful and versatile tool to study the cellular and molecular bases of mammalian cell competition at the time of gastrulation. Nice work! https://t.co/YJr9WHEcZP

[Alfonso Martinez Arias @AMartinezArias]

1/2 Early development requires fit cells. Following @MTorrescnic & T. Rodriguez, led by @JoshiFrenster we've developed a #gastruloid model #CellCompetition
https://t.co/RPgCDrmdOe
that recapitulate cell competition as in the embryo & open up experimental possibilities
