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! 🫶

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

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.

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

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
