Genes are not On/Off switches. In a new preprint we show that HDAC3 is key to establish correct transcriptional dose in development. Gr8 work from N. Stamidis @ucph.bsky.social and collab. @jamiehackett.bsky.social @gregersenlab.bsky.social . Huge thx to all authors! www.biorxiv.org/content/10.1...
HDAC3 prevents enhancer hyperactivation to enable developmental transitions
Dynamic gene regulation requires precise cooperation between transcription factors and chromatin modifiers at regulatory elements to achieve not only activation or repression, but also appropriate tra...

🧵1/14 Preprint thread! Can we predict a cell’s fate based on its dynamics? 🔮 Our new study unveils a framework for watching development unfold in real-time, revealing how a cell's shape and movement encode info about its future fate. 🔬📄 Preprint: tinyurl.com/4shf8v4x

It’s always a bit awkward to write about personal experiences. I tried to touch on what Pride means to me and ended up reflecting on heteronormativity, passing, and allyship. Thank you @slefkopoulos.bsky.social for the great opportunity! @ucph.bsky.social

It was fun to chat with @amjeve.bsky.social about my fantastic mentors and how it is to become independent at reNEW_Global @ucph.bsky.social
Transitions in development – an interview with Jan Żylicz

We met with @jzylicz.bsky.social‬ (reNEW @ucph.bsky.social) on Teams to learn more about working abroad, finding a good mentor and his career path so far:

In a new preprint with @trabelink.bsky.social, T. Moritz & @bonalditiziana.bsky.social, we find that implantation leads to rewiring of the TCA cycle to support histone acetylation turnover and exit from naïve pluripotency. Gr8 work of @elenikafkia.bsky.social D. Pladevall-Morera et al. rb.gy/clk8vm
TCA cycle rewiring underpins implantation and histone acetylation programming
Metabolism has emerged as a key regulator of stem cell differentiation and their epigenomes. This coupling is particularly evident during the exit from naive pluripotency in vitro. However, our unders...

Can metabolism regulate more than bioenergetics during human development? Our new study says YES! We show that metabolism influences cell fate choice in human naïve pluripotent stem cells, histone acetylation, and trophectoderm maturation. rb.gy/spqr9j

It was very fun to contribute to this article: "But genes are not the whole story. New research has shown the extent to which cell metabolism (...) has an important, underappreciated role in directing cell fates". www.quantamagazine.org/how-metaboli... QuantaMagazine @ucph.bsky.social
How Metabolism Can Shape Cells’ Destinies | Quanta Magazine
A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life.

I’m very excited about this collaborative project! We managed to significantly scale up and streamline human blastoid generation without the use of feeders. @leeboratory.bsky.social @grazianomartello.bsky.social @pasquelab.bsky.social and Nicolas Rivron @ucph.bsky.social
With pleasure we share our preprint reporting robust and cost-effective expansion of naive human Pluripotent Stem Cells without feeder cells. A fantastic collaborative effort with @leeboratory.bsky.social @jzylicz.bsky.social @pasquelab.bsky.social and Nicolas Rivron.
