Excited to share our preprint, reviving @kristyredhorse'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...🧵:
After 20 years, 58 generations and more than 30,000 cloning attempts, a team of researchers has hit the limit on the number of times a single mouse can be serially re-cloned

🚨 BIG NEWS: The era of in vitro human embryo implantation has arrived! 🧬
We have successfully modeled the earliest stages of pregnancy in the lab using a new 3D "organoid uterus" platform. Published today in @CellCellPress: https://t.co/GSGZiclQRb
Leverage on our human blastoid model we now establish a 3D in vitro model for studying human implantation and implantation failure: Cell https://t.co/CIFJBsaOXg Congrats to all co-authors and collaborators, especially Hongmei Wang @CAS! So proud of my former trainees Leqian Yu and Yulei Wei who have made this finally happen in their own labs! This project started shortly after we published the first human blastoid model based on naive human pluripotent stem cells and it took several years of trial and errors with different strategies. I am happy to see now it has been successfully applied to study mechanisms underlying human implantation and implantation failure. More importantly our model helps screen FDA approved compounds that hold the potential to overcome repeated implantation failure.
Despite high cell numbers and long lifespans, large animals don’t have higher cancer rates: Peto’s paradox. Elephants carry extra copies of tumor suppressor genes, while whales enhance DNA repair mechanisms! Fascinating that nature found different solutions to the same problem
Funktionsfähige Eizellen aus menschlichen Hautzellen erzeugt: Portland – Ein Forschungsteam aus den USA hat in einer Proof-of-Concept-Studie erstmals gezeigt, dass sich aus menschlichen Hautzellen befruchtbare Eizellen erzeugen lassen. Die in Nature… https://t.co/x3I0dieOIG
Scientists have for the first time ever filmed a crucial step that leads to new human life – cracking open a 'black box' of early development. @ojosnegros_sam@IBECBarcelona
