How do cells control the lumen shape and size? Check out our combined work from the
Honigmann_Lab
and
RivelineLab
where we look at the mechanical role of #TightJunctions in #lumen formation: www.sciencedirect.com/science/arti...
The images show a series of midplane cross-sections of small, spherical structures called cysts, made up of cells from a type called MDCK-II. These cysts have been genetically modified, with specific changes to their tight junctions (TJs), which are structures that help cells stick together and regulate flow between them.

Lipid imaging on the cover of @nature.com! Great times for lipid cell biology indeed. And a fantastic recognition of all the hard work by the team, especially Juan M. Iglesias-Artola and Kristin Böhlig (who made the cover). Link to article: www.nature.com/articles/s41...

New preprint from the lab! We discovered a transient fluidization in the basal region of human forebrains by tracking microdroplets in cerebral organoids.This “basal fluidization”, absent in gorilla and mouse, may contribute to greater surface expansion in human forebrains

#CellPhysics2025 @uni-saarland.de: looking forward to talking about "Mechanics of Lumina" (*) in the "Cell Collectives" session this morning.

(*) Note the use of the correct plural of "lumen".

It is with great sadness that the University shares the news of the death of Professor Sir John Gurdon, founder of the @gurdoninstitute.bsky.social

Read our tribute to the visionary Nobel Laureate and watch an interview from 2012, just after he won: https://bit.ly/4mM8o3r

Der Tag der Deutschen Einheit ist ein Grund zum Feiern. Feiern wir also und vergessen nicht: Es gibt noch einiges zu tun! 35 Jahre nach der Wiedervereinigung bestehen die strukturellen Unterschiede zwischen Ost und West immer noch:

Beautiful beasts: excited to see our first volume electron microscopy study on malaria parasites published: advanced.onlinelibrary.wiley.com/doi/10.1002/... revealing new insights into Plasmodium ookinete development. Thanks for great EMBL-Umea-Heidelberg collaboration.

Congrats Nedal @ndarif.bsky.social, Yannick, Freddy and coworkers to this beautiful project. Another great work from #SFB1129. Special congrats to first author Nedal who very recently defended his PhD at #EMBL.

Toluoltropfen in Wasser mit Aceton als Stoffübergangskomponente. Der Tropfen steigt nicht auf, da er mittels Levitation in der kontinuierlichen Wasserphase in einem Schallknotenpunkt festgehalten wird. Konzentrationen von Aceton werden mittels Schlieren visualisiert.

See this? This = implanting mouse embryo. Usually this happens inside its mother and is invisible to us, but we can actually watch implantation ex vivo with the hope of understanding why implantation goes awry in embryos of older women. A 🧵...

Another #preprint: "Elasticity and plasticity of epithelial gap closure", from the #PhD work of Maryam Setoudeh:

arxiv.org/abs/2509.05110

This one required a lot of (I think) beautiful #mechanics!

We recently submitted part of her #PhD work, "Elasticity and plasticity of epithelial gap closure" arxiv.org/abs/2509.05110: the summary of some very nice #mechanics is below. Stay tuned for more!

Now out in final published form - with a new title "Mechanical control of cell fate decisions in the skin epidermis" and simulations/quantifications! See below for thread of how unbalanced tensions can bias fate choices in minimal 3D models of tissues! www.nature.com/articles/s41...

Happy to share the latest work from Preeti Sahu, with Adriana Sanchez-Danes on the biomechanics of cell fate choices during tumor initiation! We implement/test a 3D vertex model with proliferation and fate choices for multilayered tissues! See 🧵 below (1/n) bit.ly/3ZXxJzk

How do cells navigate up gradients of adhesive proteins?
🤔

Termed "Haptotaxis", this effect is ubiquitous in cell migration, but it's mechanism was poorly understood

We show that passive friction directs cells & explains complex trajectories on gradients

Our latest preprint! Into morphogenesis, Yap, ECM, signaling, vertex models, feedbacks/robustness? There is something here for everyone. We discovered a positive feedback loop that extends inner ear canals, and a built-in mechanism that shuts it down when morphogenesis is done. tinyurl.com/464wsjhd

For this #FluorescenceFriday, a gorgeous image of an adult mouse kidney labeled with AQP2 and alpha SMA antibodies. AQP2 (green) marks the collecting duct and distal connecting segment while SMA marks the arterial tree. Courtesy of talented postdoc Sarah McLarnon.
Image of a fluorescently labeled adult mouse kidney showing AQP2 staining of collecting ducts and connecting segment in green and alpha SMA staining of the arterial tree in magenta. The collecting ducts look like squiggly branches.

Excited we can generate nephron cells for preclinical trials. We will continue to perfect the proximal tubule model and are going deep into understanding nephron injury programs and following up on druggable targets that could solve acute kidney injury and maladaptive repair.

A Nature Communications paper from Nils Lindström's lab at USC Stem Cell identifies key molecular switches that generate distinct cell types within the kidney’s filtering units, or nephrons. The lab is getting closer to making therapeutic kidney cells on demand! stemcell.keck.usc.edu/scientists-u...

Are you interested on how regenerating tissues transit between stages? Am sharing here our work showing that during #Xenopus tail regeneration, tissue stiffening activates a Piezo1-Yap1 mechanosensitive cascade to allow wounded epithelia to transit into regenerative states!
