💡 Have you ever wondered how #circulating #tumor cells squeeze through narrow #capillaries during hashtag#metastasis ?

💥 We did, check out our latest publication just out #NatureMaterials: rdcu.be/eZHxJ

Thanks 🙏

A long story initiated back in the old days when I was a post-doc in the lab with my science buddy @follainga.bsky.social . Matured and bonified by Valentin during his PhD to shape the story, helped with Zeynep Yesilata for revisions during her early PhD + many others PhDs and post-docs in the lab.

💥finally here💥. Our latest manuscript (@goetzjacky.bsky.social lab) is out in @natmater.nature.com. We show that cell viscosity drives the metastatic potential. A project handled by former PhD student Valentin Gensbittel, help from Zeynep Yesilata & many labmates! www.nature.com/articles/s41...

Ysterday was quite an amazing day for me and the TBL lab @goetzjacky.bsky.social .
Amandine Dupas (my first PhD student) brilliantly defended her PhD with an excellent presentation and an outstanding scientific discussion ! I could not be more proud. Congratulations Amandine this is well deserved 👏

It has been a privilege to assist to the Ruban Rose award ceremony with Research Grand Prize awarded to @goetzjacky.bsky.social at the Hôtel de Lassay.
Thanks for this amazing time and always sharing the light with your team 🙏.
We are very grateful to the Association Ruban Rose for their support.

📢Internships on cellular nematics!

🔬Come for the pretty images, stay for the cool physics: each project combines in vitro experiments with advanced microscopy and image analysis.

📧Feel free to DM or email me with any questions.

Very happy to share the beautiful cover of @cp-trendscancer.bsky.social that is designed based on our review article on #platelets and their role, usage and targeting in #cancer and its #therapy

Just back from an awesome #zebrafish meeting in #Toulouse. Vibrant and caring French community around one of our favorite model system 🐠🦓

With Zeynep YESILATA Laurie Nemoz-Billet & Naël OSMANI, we presented some of our current work using that model

👏

Amazing ! Beautiful work 👏

Exciting new #Zebrafish research from the #WeinsteinLab, led by Jong Park!

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

Thanks !

🎉Beyond happiness... this was a long story ! Well handled by our former PhD student Valentin Gensbittel. Initiated back when I was a post doc and now finalized as a tenured researcher in @goetzjacky.bsky.social lab ! If you can't wait the initial version is still here www.biorxiv.org/content/10.1...

Exciting times in the lab 🤩
Today, we have received the first #deformability #cytometer in France 🇫🇷
We will be measuring #mechanics of many cell types and conditions 🧫, and coming from various samples ⚙️
