Husband - Dad of 2 - Scientist 🇨🇱 Chilean expat. I love to study how cells walk & talk. PI of the @cellcommlab.bsky.social #CellMigration #CellComm #calciumsignaling #organelles 🧪🔬

This epic paper, which has been a heroic 10 year journey for the lead author, Ricardo Barrientos, is finally out in Cell today! Many thanks to all co-authors, especially Billie Meadowcroft and Andela Saric for their beautiful MD simulations www.cell.com/cell/fulltex...

Basement membrane turnover controls cell shape

Basement membranes are scaffolds of proteins, like collagen, that give organs shape. During development, basement membranes must adapt to the growing organ. We infer how fast the basement membrane ada...

Watch a muscle fiber take shape. 🔬 This microscopic video captures a muscle cell fusing with a developing muscle fiber, with cell membranes visible in purple and yellow. The Rando Lab uses live-cell imaging to understand how cells coordinate muscle regeneration. Credit: Tamas Nagy/Rando Lab

Decades ago in 🇨🇱 cellbio meeting immunologist delivers a ppt with 90% immuno and 10% cellbio. Everyone baffled. 1st row sitting senior PI rise the hand: -why did you come to this cellbio meeting? -yeah I wonder the same sometimes (laughs nervously) -I'm not joking, why?! This 👇🏽 is magnificent too

Speaker refused to divulge the name of compound X in Q&A after his ASCB talk. Questioner [who will be known to many cell biologists] blew a raspberry into the mic and gave the speaker the finger.

I know for a fact that this list is 100% human-generated! For that reason, there are almost certainly some excellent research that I've missed.... Drop me a message if you have any suggestions that I should add to the list.

📢Check out our latest preprint list on FocalPlane In this list, we focus on the latest tools and techniques in imaging, including sample prep, probes, hardware and software. focalplane.biologists.com/2026/06/26/m... Let us know if you've been reading a preprint that we should add to our list.

The array of organs in the animal body differ dramatically in their architecture, but cell-cell adhesion mediated by cadherins is a common principle. Our lab usually focuses on epithelia but cadherins are also active in migrating mesenchymal cells like these migrating testis myoblasts 1/n 🧪

We kicked off today the 1st session of the Focal Plane #CellMigration webinars Brilliant talks by @juanmagararc.bsky.social , @kyohalie.bsky.social & @djcohen.bsky.social Tks to Helen @focalplane.bsky.social for organization & support. Looking FWD to the next one @valeriaventurini.bsky.social !

1 week to start🔥 New @focalplane.bsky.social webinar series focused on #CellMigration, register & join us▶️, it will be fun! pls spread the word, in the next one, ECRs could apply to show their work ;) ▶️ to register: focalplane.biologists.com/2026/05/29/n... @dgz.bsky.social @the-node.bsky.social

Cellular structure self-organizes through an interplay between internal mechanisms and external cues. The single-celled suctorian P. collini builds a trap structure to capture large prey using microtubule feeding tentacles, creating feedback between cell morphology and prey availability.

Seeking a post-doc for the LaJoie lab at the Human Technopole, Milan, Italy! We are looking for candidates from the fields of biochemistry, cell biology, and proteomics, who are interested in studying protein interactions of the nucleus 🤓 lnkd.in/dTG2CgXF
