#FluorescenceFriday Proud of our the last paper @cellcommlab.bsky.social & 1st one of @jboixcampos.bsky.social We continue to study #CellMigration & how cells decide where to go: ↖️↗️⬇️? (movie of the actin #cytoskeleton) Full www.science.org/doi/10.1126/... @focalplane.bsky.social @science.org 🧪🔬

#HappyNewYear ! Let's start 2026 with a @cellcommlab.bsky.social paper How many branches is OK during #CellMigration? It depends on the #cell: for ex. immune cells are just fine. In collab. w. #NirGov @hfspo.bsky.social Full www.science.org/doi/10.1126/... @focalplane.bsky.social @science.org 🧪🔬

How do migrating cell groups balance force and flexibility? Our new preprint shows that RhoGAP15B downregulates RhoA–Myosin activity to stabilise protrusions and enable efficient collective migration in vivo. Happy New Year! www.biorxiv.org/content/10.6...

‼️🚨Hi all! The next Bioc Soc Membrane Contact Site Meeting will be in Chepstow, UK 28-30th Sept 2026. Fantastic speakers with talk slots still available. Sign up & abstract submission now open - limited spaces so register early! Hope to see you all there. Please share + RT 🙏

Hot from the #preprint Leukocyte + #CellMigration + physics = cool Microtubules enable torque-based steering during dendritic cell migration. Actomyosin contractility is required for noise-modulation strategy used by neutrophils. Full @biorxivpreprint.bsky.social www.biorxiv.org/content/10.1...

Still posting cytoskeleton videos, it seems. Actin this time. Sample: Lifeact-eGFP in HeLa cells. Modality: Airyscan confocal Timestamp is mm:ss and the scale bar is 5 µm.

It’s time to talk about epithelial geometry and cancer. How can the architecture of an epithelium affect how tumors will grow and spread? In this thread, @jorgealmagro.bsky.social

Even if "provisionally" accepted, those are the best words/news I've heard for quite a while... Here some #blebs to "provisionally" cellebrate. Let's see this #cell dance under the microscope. @focalplane.bsky.social #fluorescencefriday #microscopy 🧪🔬

I'm back at regulardly doing some live imaging so I have new little videos of actin in the immune synapse.

The law of the jungle. Interactions of cells in a collective lead to global rotation. In 80% of the case HUVEC cells turn clockwise. How many cells does it take for this to happen?

Do you want to do some frontier of knowledge research? There's still time to register for the next webinar of @hfspo.bsky.social By far one of the best agencies I've worked with for my beloved HFSP project, even if it's a bumpy road...no risk no glory... www.hfsp.org/hfsp-events/...

What a crazy cool paper! First author @pierreucla.bsky.social with a large crew knocked it out of the park.

I won't talk about NMeth @natmethods.nature.com forever (probably), but I do want to brag a bit about the November focus issue on cell segmentation and tracking, which is many ways is my last hurrah (and final editorial) for the journal. I am so proud of these papers!! www.nature.com/nmeth/volume...

This week's #FluorescenceFriday, we'll be treated with one of the classical models of #devbio, the neural crest cells. Here is a beautiful video of neural crest cells with GFP-tagged focal adhesion kinase (🔵) and LifeAct-RFP (🟣) migrating on a Fibronectin matrix. 📹: Adam Shellard

I love to see the endoplasmic reticulum (ER, cyan) hitchhiking over microtubules (MTs, orange). Also the membrane dynamics are lovely. It's been a while, but here we are for a late #fluorescencefriday with some #microscopy #scicomm #scisky @cellcommlab.bsky.social focalplane.bsky.social 🧪🔬

Job alert! We are looking for a bioimage analysis to work in an image analysis core facility in beautiful Paris. Can I ask you to share this opportunity with your networks? See also on the forum: forum.image.sc/t/research-e...
