- Reposted by Alexandre MayranUsing fluorescence live imaging and an in vitro implantation model, we show that human embryo attachment begins with direct cell fusion via syncytin-2–MFSD2A interaction. With @hansclevers.bsky.social. Great work by @tnoordzij.bsky.social & @martinacelotti.bsky.social www.biorxiv.org/content/10.6...

- Reposted by Alexandre MayranLovely little pre-Christmas present to see this out @natcellbio.nature.com! Some 🔥 new results in here since the biorvix incl (1) a new RARE-GFP reporter ✳️🙌, (2) additional NMP quantification 🔢, (3) no neural tube patterning on RA inhibition 🙅 etc. Enjoy! 😍 www.nature.com/articles/s41...
- Reposted by Alexandre Mayran🎉 Our deconstructed, stem-cell–based approach to studying signaling centers and limb-development cell types is out! 🥳 So nice to see it in its final form after the preprint— and huge thanks to the community for all the enthusiasm and interest since then! www.science.org/doi/10.1126/...

- Reposted by Alexandre MayranThrilled to share our new review in Current Opinion in Genetics & Development on TE driven innovation in gene regulation🤘. I am honored to be part of this with two major TE aficionados @cedricfeschotte.bsky.social and @trono-lab.bsky.social #TEsky #TEworldwide authors.elsevier.com/c/1m6MC,LqAZ...
- Happy to present the final version of our Cadherin and gastruloid manuscript, online at @cp-cellreports.bsky.social. www.cell.com/cell-reports... Initially in BiorXiv (www.biorxiv.org/content/10.1...) 1/12
- Here, we could confirm that gastruloids lacking N-Cadherin self-organize correctly, in fact even better than their wildtype counter part as they form polarized somitic tissue without requiring exogeneous extra cellular matrix such as matrigel. 2/12

- Reposted by Alexandre MayranLooks like private funders, HHMI,CZI etc., are not going to “save” US research. Europe is setting up mechanisms to attract US researchers & it may work. But, common, target junior talent, don’t shower money on superstars who will be flying professors & return to US when the science winter passes.
