#OPENACCESS: Cells don’t just communicate through calcium waves; nematic cell alignment shapes how information propagates. Winterstrain et al. show that nematic defects can desynchronize signaling, with calcium waves traveling fastest when perpendicular to tissue orientation.

Nematic cell alignment directs calcium waves in an epithelial monolayer

Tissues rely on supracellular signals to coordinate their cells over a long range. Two such tissue-scale cues are calcium waves and patterns of cell-cell alignment or nematic order. During wound…

💫 Our paper is now published at @natcellbio.nature.com! So excited about this work done during my PhD at @embl.org in the group of @nicolettapetridou.bsky.social along with our great collaborators! 🐟🎉

Glad to see this out in its final form! www.nature.com/articles/s41... What changed since the preprint? Wonderful experiments disentangling the effect of receptor binding vs tissue porosity on Nodal diffusion, plus one of the smoothest review experiences! Thanks @natcellbio.nature.com & reviewers 🙏

This is going to be marvellous — looking forward to three inspiring days of exchange and discussion on #cellularinterfaces @sfb1348.bsky.social @uni-muenster.de

The @sfb1348.bsky.social Meeting “Mechanochemical Signals at Cellular Interfaces” is just around the corner! We are excited to welcome an outstanding lineup of international speakers to #Münster for three days of inspiring scientific exchange and discussion. @uni-muenster.de

All you ever wanted to know about how to analyse the nematic nature of cellular tissues is right here 👀👇🏼! Bonus #1: we did it for many cell types and uncovered unexpected defect behavior 🐌 Bonus #2: for theoreticians looking for parameter values for your simulation🧑🏼‍💻 tinyurl.com/2s399yen

New study on topological defects develops a mechanochemical model integrating morphogen concentration and hydrodynamic flow, reproducing experimental collective motility and revealing viscosity, activity, and alignment strength as key factors governing defect-mediated transport.

Mechanochemical coupling regulates defect dynamics in active nematics

Active nematics offer a versatile continuum framework for nonequilibrium collective phenomena, such as collective cell migration and tissue morphogenesis. However, the dynamic evolution of active…

A sea anemone looks very different from a coral, despite belonging to the same broad biological group. A new study from EMBL researchers and their colleagues sheds new light on how diversity arises in body shapes in the animal world. www.embl.org/news/science...

🔥Exciting new paper from the Ikmi group @embl.org! The authors identified a set of mesoscale mechanical modules that can be used to predict species-specific shapes by combining a comparative analysis of cnidarian larval morphogenesis with active surface theory #morphogenesis #cnidaria

Our study on shape diversity in cnidarians is now published. The final version includes extensive new data that substantially extend the original bioRxiv preprint. Congrats to everyone who contributed to this work! www.cell.com/cell/fulltex... @embl.org
