In developing embryos, cells move a lot! Plenty of that movement is random. Is random cell mixing a feature or bug for tissue patterning? Turns out, it’s both! Excited to share the 1st preprint from my postdoc w/ Sean Megason @seanemcgeary.bsky.social and Allon Klein. 1/20 doi.org/10.1101/2025...

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

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!
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!

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.

Stay tuned for the paper to come soon !
Beautiful experimental data falling on the mathematical model, no fit needed 🤩

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.
