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! 🚀

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...🧵:

📣 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

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)
