Looking forward to an exciting @sfb1348.bsky.social seminar with Lucia Baldauf @ucl.ac.uk on January 8, 2026. She will speak about "Illuminating Forces in Living Tissues". More info: www.uni-muenster.de/SFB1348/en/i... Everyone's welcome!

Actomyosin-dependent assembly of the mechanosensitive machinery from adherens junctions triggers actin polymerization and organization In vitro reconstitution shows how mechanosensitive adherens junction proteins link actomyosin contractility to actin assembly.

Interested in working in an exciting project on morphogenesis, in a great environment for imaging? 🪰🔬

Super proud to be part of SFB1348 — and excited to share that I now officially have my own lab in Münster! 🎉🪰

We’ll study #cellbio & #morphogenesis, focusing on organ sculpting and #chirality in #Drosophila.

I’ll soon hire my first #PhD student — feel free to reach out!

Super cool work from our institute!

Supracellular control and coordination of tissue morphogenesis, through supracellular actomyosin assemblies, that is what my lab @cellbiol-mrclmb.bsky.social @pdncambridge.bsky.social and I like to dig into at the moment! Fascinating and beautiful! journals.biologists.com/dev/article/...

Epithelial biology: Holding the corners together A new study reveals that the Drosophila follicular epithelium opens its permeability barrier to allow passage of yolk to the oocyte by relaxing, not actively pulling open, cell vertices. This work res...

Great Dispatch article by @tarafinegan.bsky.social on our new paper by @theajacobs.bsky.social in @currentbiology.bsky.social - thanks for condensing our findings so clearly and nicely!

This dot is a region that intersect multiple cell junctions in an epithelia. These dots act as tiny anchors of cell contacts and they’re critical for epithelial coherence during homeostasis AND development.

I’m @katecavanaugh.bsky.social and I’ll be your guide on this 🧵 about tricellular vertices.

Afadin mediates cadherin-catenin complex clustering on F-actin linked to cooperative binding and filament curvature Afadin strengthens adherens junctions by stabilizing cadherin-catenin complex clusters on curved F-actin.

Some happy news. Pleased to see our paper showing how afadin strengthens cytoskeletal engagement by the cadherin-catenin cell adhesion complex out in Science Advances: bit.ly/3EFpD6h

Our new paper by @theajacobs.bsky.social in @currentbiology.bsky.social shows how relaxation of tension, rather than active actomyosin-based force, allows opening of cell #vertices to increase #epithelial permeability shorturl.at/Wnb2n
