💥 🚀 New preprint! 🎉🥳 How do hundreds of organelles organize themselves into near-perfect patterns inside a cell, without a blueprint? We dive deep into how basal bodies (BBs) self-organize in MCCs - and how actin actively tunes their dynamics into order 🍪 🧵👇 (1/17)

Excited to share our latest paper! We found that large pieces of the human genome can transfer between cells upon direct contact, endowing recipient cells with heritable phenotypic changes. @cp-cell.bsky.social (1/7) www.cell.com/cell/fulltex...

1/ Our new preprint is out today.🎉 It started from a surprising control experiment while studying how talin binds vinculin. We were using the widely adopted A50I vinculin mutant to disrupt talin binding — but unexpectedly, it still bound talin. www.biorxiv.org/content/10.6...

FANTASTIC work from @myosincity.bsky.social and @pwoakes.bsky.social on smooth muscle myosin II filament dynamics! Vascular Smooth Muscle Myosin 2 Filaments Dynamically Assemble and Stabilize During Induced Contractility www.biorxiv.org/content/10.1...

Happy #FluorescenceFriday! Just some random data I collected from a while back, actin and myosin in a U2OS cell imaged on our lattice light sheet microscope.

Very pleased that after a rigorous (and lengthy) review process, our paper visualizing how myosin generated forces modulate actin filament structure for mechanosensitive recogntion by α-catenin has appeared in @nature.com : www.nature.com/articles/s41...

What if you got to work with some of your best friends on a science project? I can't publish how fun this was, but I can show you the data (🧵)! Last week, we posted our second neutrophil swarming paper to bioRxiv and I wanted to post my favorite videos here~ www.biorxiv.org/content/10.6...

Out in @natmethods.nature.com: More dyes. They work. Quite well. And blink. Pick the one that fits your target, your technique, and your labeling density. With too many collaborators and institutes to list, but anchored at @hhmijanelia.bsky.social www.nature.com/articles/s41...

How do proteins find their way to the cell's leading edge? @jimgalbraith27.bsky.social & @cathygalbraith.bsky.social break down how bleach line, FLOP, single-particle tracking, FCS & iPALM reveal intracellular fluid flow and an actin-myosin compartment barrier. doi.org/10.1038/s414...

is there a direct crosstalk between actin and vimentin intermediate filaments? Our work shows that vimentin promotes actin assembly by stabilizing ATP-subunits at the barbed end. Fantastic work done by @lilianpaty.bsky.social with @romet-jegou-lab.bsky.social www.biorxiv.org/content/10.1...

Presenting a talk the ASCB @ascbiology.bsky.social #CellBio2025 meant a lot to me, a new guy in the field. Thanks to everyone whom came for the session, and special thanks to the ones whom dropped me kind encouragements before my talk! 😊

Today, our animation synthesizing decades of research on actin-mediated endocytosis in budding yeast was published: journals.biologists.com/jcs/article/... The result of a fantastic Iwasa-Drubin lab collaboration. @margotriggi.bsky.social @jiwasa.bsky.social movie.biologists.com/video/10.124...

Hey everyone and fellow #actin people! Here's a preview video for my upcoming talk at #cellbio2025 @ascbiology.bsky.social next Wednesday at 10am! Because it's gonna happen on the last day, so I promise to be a little funny, and I might even throw in a song and dance! And some nice data too.

Realized this morning that my submission got selected for Yale's Beauty in Science 2025 exhibition! Seeing the live-assembly of filopodia projections by formin mDia3 in mast cells got me really stoked back then! #FluorescenceFriday

🧵5/6 — The Big Picture EndoNB works on endogenous proteins. No rare antibodies. No overexpression. It’s scalable and ready to explore the 1000+ surface proteins we’ve barely studied. We’re done understanding vesicular trafficking by looking at a handful of model surface proteins.

🧵1/6 — Preprint Alert! I am super proud to present the latest work of our lab. Earthlings and those just visiting, I introduce you…. EndoNB: A better, smarter and versatile way to study the dynamics of cell surface proteins. 🧪 www.biorxiv.org/content/10.1...

My first post on Bluesky! Very excited to share our work just published in @science.org. We find that “Interphase cell morphology defines the mode, symmetry, and outcome of mitosis” - in angiogenesis and other tissues! www.science.org/doi/abs/10.1... www.science.org/doi/abs/10.1...

We show that under low ahesion conditions Tensin 1 forms endogenous condensates to store inactive adhesion components. These can be released upon stress-mediated Tensin 1 phosphorylation to regulate adhesion dynamics.

Happy to share our Tensin 1 phase separation project is now on bioRxiv. www.biorxiv.org/content/10.1... This wouldn't be possible without @johannaivaska.bsky.social @ivaskalab.bsky.social #VattulainenLab #MSCA by @ec.europa.eu @turkubioscience.bsky.social @inflames-flagship.bsky.social

New preprint alert!📣 @midibu.bsky.social and team take a deep dive into Tensin1 liquid-liquid phase separation (LLPS) and the mechanisms of how it regulates adhesion dynamics! Check out the preprint here: www.biorxiv.org/content/10.1... @johannaivaska.bsky.social

Unlike eggs & mitotic cells, in adherent interphasic cells the centrosome is NOT positioned by a balance of forces along #microtubules, but by cell shape organization around the #centrosome: rupress.org/jcb/article/... @lblanchoin.bsky.social @manuelthery.bsky.social @gelinmatthieu.bsky.social

Progress on the quest for a red mStayGold! Just out: mScarlet3-S2, a new photostable red FP derived from mScarlet3: www.researchsquare.com/article/rs-5...

Incredible 4Pi and pan-expansion imaging of the Golgi 👇

Thanks for selecting my entry. This is one of my favorite movies captured. I’m very flattered 🙂

Hi everyone, because it's my first time winning any contest, I ain't gonna lose this wave of opportunity to talk about it 👀. I got tweeted, but I feel the need to publicize this here too. I won the @ascbiology.bsky.social ASCB 2024 Image Contest! Thanks for selecting my entry!

It was a humbling experience being able to talk to people about our works at the ASCB. I’m flattered that I had plenty audience for me to keep going without break for ~6 h straight and going overtime! Thanks, everyone 🥹 #CellBio2024 @ascbiology.bsky.social

#FluorescenceFriday An old video of a cute mast cell (RBL-2H3) exhibiting cortical waves of active Cdc42 after getting treated with cytochalasin-D overnight. Sorry not sorry to kill #actin hehe. #TIRF 4 s per frame acquisition, 8 fps, 32× real time.

Look at these distinct clusters exhibited by N-WASP and Arp2/3 ! Is branched #actin polymerization the sole driving force for nucleating cortical actin waves? Cross-talks within the actin network can be messy, so how can we study such complexities? #CellBio2024 @ascbiology.bsky.social

Mix two motors of opposite polarity with microtubules and they will partition space ! Microtubules will get organized in polar and active barriers, sorting the two motors in separated domains, leading to the emergence of a new type of patterns. #morphogenesis doi.org/10.1073/pnas... (1/n)

Before I start posting about newer results on this platform, here is a video from our most recent paper -- www.nature.com/articles/s41...

Who needs immunofluorescence? Focal adhesions (or cell feet as they were known then) were first observed in this 1975 paper by Abercombie and Dunn doi.org/10.1016/0014... This gem comes from the obituary of Graham Dunn published in J Cell Sci today. doi.org/10.1242/jcs.... 🧪

I started a list of people working broadly on cell adhesion and cell migration. I likely missed many, please drop me a message if you want to be added go.bsky.app/5Gzo7oZ
