We wrote two reviews on cell migration, published today in Nature Methods.

They provides practical guidelines how to select a cell-migration assay and how to analyze cell-migration data

“A process which led from the amoeba to man appeared to the philosophers to be obviously a progress - though whether the amoeba would agree with this opinion is not known"
- Bertrand Russell, 1976.

Organelles do NOT have a single uniform pH.
And if you think they must, because “protons diffuse fast,” this paper is for you.
A thread on why that assumption is wrong; and what we found instead. 🧵 1/n

See you at board 34 today!

I’d like to invite everyone working on engineering living materials to share this starter pack. Please drop me a message or leave a comment if you like to join the #ELMs community. go.bsky.app/RinsDZh

Hope to see you all at 10AM today!

Flagellar length control in Chlamydomonas is a paradigm for organelle size regulation. In poster 163 at CellBio2025 Sunday Dec 7, I present work by Hiro Ishikawa using a synthetic biology approach to test a length-sensing model based on diffusion of kinesin in flagella

I’m so excited to be at #CellBio2025 with my trainees! Elizabeth (#259) and Olivia (#251) have posters in Sunday’s session. Please stop by to hear about the work we are starting up in the lab looking at Rap1 GTPase signaling in epithelial migration in human carcinoma cells and in Drosophila embryos.

Attending #Cellbio2025?
I am presenting two posters, stop by if you are interested in epithelial dynamics.
Looking forward to all the amazing conversations and feedback!!

My former bench mate @joellemiere.bsky.social from the @fredchanglab.bsky.social giving a killer talk about nuclear size regulation in fission yeast at #ASCB #CellBio2025
Stay tuned for the paper to come soon !
Beautiful experimental data falling on the mathematical model, no fit needed 🤩

Super excited to share some of my work in such a great session at #cellbio2025!! If you’re at the meeting come on down, I’ll be talking about cell density and its influence on tissue fluidization during epithelial morphogenesis 🔬👨🏻‍🔬🪰

🚨 Link up with me at #Cellbio2025 ! 🚨 Excited to present the majority of my postdoc work in the Physical Cell Biology from Molecules to Organisms Minisymposium. Thanks to the organizers for putting together such an exciting session 🤩

Featuring @katecavanaugh.bsky.social @yusuke-mori.bsky.social @fengtongji.bsky.social @liamjrussell99.bsky.social Gavin Schlissel, June Ho Hwan, Yuxuan Rain Xiong, Rohit Joshi, and myself!

Sun 10AM–12PM, Room 120 (The app is missing the first few talks, but I assure you talks start right at 10AM!)

Looks like I'm just an F0 founder in a tank all by myself.

If you're at #cellbio2025, @atmolines.bsky.social Hernan Garcia and I invite you to attend our Minisymposium “Physical Cell Biology from Molecules to Organisms” for incredible talks on epigenetic mechanical memory, viscoelasticity, cortical flows, morphogenesis, tissue wetting, size scaling, et al!

The #cellbio2025 is starting this week! I’ll be giving a talk on the first 1st day, in the session organized by @iaincheeseman.bsky.social and @abbybuch.bsky.social (Thx for the invitation!). If you’re interested in #oocytes, #proteostasis, and #aging come by to attend! @ascbiology.bsky.social

Come find out how to make your science more accessible. Hear and touch mitosis during my talk. @ascbiology.bsky.social #cellbio2025 #mitosis #midbody #tactilelearning

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.

Any other shoalmates in attendance? #cellbio2025

If you will be at @ascbiology.bsky.social #CellBio2025 this coming week, let’s connect! I'm giving a talk on Tue Dec 9 at 10 AM in the “From Mechanisms to Therapeutic Insights in Neurodegeneration” session and a poster on Mon Dec 8 in the “Organelles – Endosome and Lysosomes” session. See you there!

Cells can hunt prey, solve mazes, and learn from past experience. Does this mean they can think, at some level? Find out more at our upcoming session on "Cell Behavior and Cognition" at the ASCB/EMBO #cellbio2025 meeting, Saturday 1-3 pm rm 115.

Attending #CellBio2025? Come see the Cohen Lab - Monday will be a busy day for us, including my theatrical debut in WICB "Scripts of Success" skits!

Presenting at #cellbio2025 this week? Please post your presentation info here on Bluesky so we can like and share!

Talk: Sun 11:21 AM, Room 120, Minisymposium: Physical Cell Biology from Molecules to Organisms, "Tissue fluidity: A double-edged sword for multicellular patterning"

Poster: Tues 2:15 – 3:45 PM, Board No. B034

Looking forward to seeing everyone at #cellbio2025! Excited to share new work from my postdoc to measure, model, and control the interplay of tissue fluidity and multicellular patterning in a living organism. Come see me at my talk or poster (details below), or DM me if you want to meet up!

Tissue fluidity mediates a trade-off between the speed and accuracy of multicellular patterning by cell sorting The organization of cells into spatial patterns is a fundamental aspect of multicellularity. One major mechanism underlying tissue patterning is adhesion-based cell sorting, in which a heterogeneous…

Too fluid, too rigid, no patterning. Garner et al. identify tissue fluidity—how freely cells move within a tissue—as a critical regulator of adhesion-based cell sorting. Read their study to learn how tissues can tune their fluidity to enable patterning.

Who's going to #cellbio2025 in Philly? I am a PhD candidate and molecular biologist studying regeneration in Hydra vulgaris, an animal that can grow back its entire body. Looking to transition to industry next year. Let's connect!

Just one week away until #CellBio2025!

Please plan to join us for a sUPeR speakER lineup at the #EndoplasmicReticulum Minisymposium!
