Wow! So excited to see on cover #MBoC #ASCB in Forces On and Within the cells issue. Vimentin expressed highest in epithelial leader cells and studied its role in leader cell mechanics. For interested ones, here is the link www.molbiolcell.org/doi/10.1091/... Thanks @ascbiology.bsky.social

New paper out @natcellbio.nature.com! In embryos, immune cell migration is guided by the surrounding tissue flow. In turn, tissue flow is captured by active wetting theory, generalized to include influx from the upper cell aggregate! Check the thread below! 👇 www.nature.com/articles/s41...

Tissue flow acts as a guidance cue for immune cell polarization and directional migration - Nature Cell Biology
Le et al. show that in Xenopus embryos, local ectodermal tissue flows provide a directional cue that polarizes and guides embryonic myeloid cells migration via cell-on-cell interactions.

My PhD work showed that vimentin is not only a passive marker of EMT, but plays an active role in collective migration, controlling the mechanics of epithelial leader cells. I am grateful to my supervisors, Rene-Marc & Benoit Ladoux, as well as to all the co-authors. www.biorxiv.org/content/10.6...
