@nicolasrivron.bsky.social and I look to recruit a postdoc through the VIP3 rogramme to investigate post-implantation development of blastoids. Contact us if you are interested, and let your colleagues who could be interested know!

I'm now on Bluesky!🤗 Excited to share our preprint, reviving Kristy Red-Horse's interest in the placenta from her PhD ~20 years ago! We find using 3D imaging that the mouse placenta is far more invasive than previously thought. Furthermore, we find a surprise from our favorite chemokine CXCL12...🧵:

Hi all! 👋 leeboratory.bsky.social and I are recruiting a VIP³ postdoc to join our teams and decode the genetic logic of how blastoids transit to the post-implantation stage. MolBio, genetics and computational approaches. If this sounds like you (or someone you know), we’d love to hear from you! 🚀

📣 New Perspective out in @natcellbio.nature.com! With an interdisciplinary team of scientists, ethicists & lawyer we propose embedded ethics as a framework for navigating the complex ethics of human stem cell–based embryo models. www.nature.com/articles/s41... Free full text link: rdcu.be/fckmY 🧵

Following several years (!) of discussion and rumination, our team of excellent colleagues - Martin Pera, @nicolasrivron.bsky.social, @amartinezarias.bsky.social, Karen Sermon and Nienke de Graeff - have published a new ethical perspective on SCBEM #embryomodels rdcu.be/fcklG [1/5]

Watson was deeply influential to me as a genomicist, but not how you may assume From stealing Rosalind Franklin's lab notes to his frequent sexist & racist bioessentialist comments later in life, he showed how the scientific community would still worship a terrible person Don't idolize bad people

Our new manuscript, led by Emily Corrigan, examines inhibitory neuron diversity across approximately 160 million years of evolutionary divergence, as part of BRAIN Initiative Cell Atlas Network (BICAN) developing brain atlas package: www.nature.com/articles/s41...

The ethical framework for embryo models needs clarity and simplicity. The spirit of the integrated/non-integrated distinction was to more prominently regulate models that could potentially develop into a fetus. Hafez Ismaili M’hamdi discusses this. www.progress.org.uk/complexity-w...

Thrilled to announce that I am looking for a Research Technician/Assistant to join my lab @imbavienna.bsky.social. Please consider applying if you’re enthusiastic about #devbio #stemcells #teamwork and excited to help shaping a new lab! Thankful for any retweet! 🫶 imba.onlyfy.jobs/job/l6u2m980

Join us in Vienna! The line-up of speakers is ready!

Congratulations to Theresa Sommer on the completion of her PhD! Theresa, a researcher in the Nicolas Rivron Group, presented her work on “Developing a stem cell – based 3D model of the human blastocyst and its application in exploring mammalian embryo morphologies” at her PhD defense.

Our paper “A genome-wide atlas of human cell morphology” is finally out today in @naturemethods.bsky.social ! www.nature.com/articles/s41... (I tweeted about our preprint in 2023 over at the bad place, but deactivated my account, so here we go again!)

1/3 Embryogenesis requires fit cells. Here, following work from @miguel-torres-1963.bsky.social & @tristanrodriguez72.bsky.social and led by @joshifrenster.bsky.social we develop a #gastruloid model of #CellCompetition www.biorxiv.org/content/10.1... showing it recapitulates much of the embryo 🧵

Dear all, registrations are open for the Mobile Genome @EMBO workshop. Many slots for posters, short talks but also long talks for last minute groundbreaking results! Let’s meet again on Nov 4-7, 2025 in Heidelberg. www.embl.org/about/info/c...

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. tinyurl.com/5n6z9rt9

Exciting community effort for robust feeder-free maintenance of human naive pluripotent stem cells with blastoid formation potential. Collaboration with @grazianomartello.bsky.social, @leeboratory.bsky.social @jzylicz.bsky.social @nicolasrivron.bsky.social tinyurl.com/5n6z9rt9

A pleasure for Emiel Van Genderen and myself to be able to contribute to this study that helps build solid foundations for conscientious modeling of human development through robust and efficient protocols. Doing science together with such people is a privilege. Thanks @grazianomartello.bsky.social

We are happy to contribute to this exemplary collaborative study aimed at improving the efficiency of working with human naïve ESCs without MEF feeder cells. With @grazianomartello.bsky.social‬, @jzylicz.bsky.social, @pasquelab.bsky.social, and @nicolasrivron.bsky.social tinyurl.com/5n6z9rt9

The deadline to submit your abstract for a talk at the 2025 SY-Stem Symposium has been extended to January 22, 2025. Registration deadline remains on February 15th. For more details and to submit your abstract, visit: www.sy-stem.org We hope to see you there! #SYStem2025

Join us in Vienna! A symposium dedicated to young scientists doing stem cell research with most talks by First authors in the transition to independent positions!

Have you ever wondered how your back formed? The human embryo makes a neural tube (future spinal cord) and somites (trunk muscle/bone) from ~d20. They’re formed at the same time and place, so we used human Trunk-like Structures (hTLS) to investigate their ‘co-development’… (1/7)

Thrilled & immensely honoured to receive the Italian Science Fund (FIS) Starting Grant. We will uncover the mechanisms underlying HSV-1 latency and reactivation in human, disease relevant, cells. Postdoc positions in virology and human stem cell biology @humantechnopole.bsky.social available soon!

The ISSCR invites all students and postdoc members to create their own session at #ISSCR2025! Choose your own topic and showcase recent developments and scientific breakthroughs that you’re passionate about. Learn more 👉 bit.ly/3Op2MxB

Happy New Year! I look forward to the #ISSCR2025 annual meeting in Hong Kong and hope to see you there to talk about how to use #blastoids and all other stem cell based embryo models to make important scientific and medical discoveries! invt.io/1txbejpdn2u @isscr.org
