Long-term imaging of cell divisions in human preimplantation embryos - Nature Biotechnology An optimized approach for live imaging of human embryos enables visualization of mitotic errors during blastocyst development.

This is an excellent news and views article from Corentin Mollier & Jean-Léon Maître @maitrejl.bsky.social

Thrilled to see this published!

Well done Ahmed on spearheading a project revealing mitotic errors in human embryos arise much later than anticipated.

Thank you to collaborators @bensteventon.bsky.social Leila Muresan and all of the wonderful teams at Bourn Hall and Create Fertility clinics!

We are recuiting two new Associate Professors here in Oxford Biochemistry. Come join us! Reach out to me if you have any questions. Please repost! tinyurl.com/mr3m7bd3

Cell-type-specific functionality encoded within the intrinsically disordered regions of OCT4 - Nature Communications Here they perform a systematic dissection of OCT4 and reveal how intrinsically disordered regions can be used to serve specific functions during reprogramming and embryonic development. This can be exploited to engineer more efficient and specific reprogramming factors.

Hot off the press!

Mechano-osmotic signals control chromatin state and fate transitions in pluripotent stem cells - Nature Cell Biology McCreery, Stubb et al. show that mechano-osmotic changes in the nucleus induce general transcriptional repression and prime chromatin for cell fate transitions by relieving repression of specific differentiation genes.

How do #stemcells integrate information to coordinate fate decisions? Delighted to finally see our work showing how growth factors regulate the mechano-osmotic state of the #nucleus and #chromatin to control #pluripotency exit out! www.nature.com/articles/s41... see 🧵 👇

One of our favourite tabs is Resources: we're listing all of our datasets, codes, beginning to upload and make accessible raw imaging data and lab protocols. Please check it out, we hope this is useful!

Today we had our lab retreat at the Eddington Postdoc Centre for the first time in a while!🧪
We had so much fun combining workshops and team-building activities, and we definitely made the most of our time together.
Do you do retreats in your lab? What are they usually like?
We will read you below!👇

Last Friday, we said goodbye to our amazing summer student, Yiping! Thank you for your hard work and bringing great energy to our team this summer. Wishing you the best in your next chapter!☀️

Protocol for immunofluorescence detection and quantification of phosphorylated SMAD proteins in human blastocysts The transforming growth factor β (TGF-β) signaling superfamily includes NODAL and bone morphogenetic protein (BMP) signaling, which lead to the phosph…

Our protocol with all the details you'll need to detect and quantify phospo-SMAD proteins in your (human) embryo, is finally out today @cp-starprotocols.bsky.social.
Thanks again to my wonderful co-author @toddfallesen.bsky.social and the @niakanlab.bsky.social.

This project has been very special to me. I want to thank James @lab-turner.bsky.social who gave me the chance to build my own research line outside of the lab's main focus on sex chromosomes, and to our collaborators Chris Barrington, Clare Critcher, Waz Varsally, Greg Alanis @niakanlab.bsky.social

Delighted to see this out! Human embryos depend on FGF/ERK signalling to specify epiblast versus primitive endoderm cells. Well done Claire Simon and the lab for their contributions! Many thanks to Mary Herbert @josh-brickman.bsky.social @cwhanna.bsky.social labs for brilliant contributions!

Very happy to see this nice collaboration with @niakanlab.bsky.social bear fruit. Beautiful work by @clairesimon.bsky.social culturing human embryos in the presence of FGF/ERK stimulation/inhibition. www.nature.com/articles/s41...

Very sorry to hear of the passing of Roger Pedersen. He was an outstanding developmental and stem cell biologist & helped to establish the Cambridge Stem Cell Institute. Our thoughts are with his family.

Very sorry to hear of the passing of Professor Roger Pedersen, whose visionary leadership helped establish the @scicambridge.bsky.social. I will never forget how Roger personally taught my group how to dissect early post-implantation mouse embryos; watching him at the microscope was truly inspiring

Thanks very much for an outstanding talk Margarida!

Congratulations Busma and the Loke CTR team!!
