Lovely feature on the spectacular theoretical research led by my brilliant friend and colleague Anna Erzberger 🤩
Our cells are experts at navigating inherently noisy and complicated environments.
EMBL researchers are using theoretical physics approaches to uncover fundamental principles behind how cells use complex information to self-organise.

A quick digest :
#Cellularization runs on two separable modules:
🧭 MTs + #MTOCs → spatial patterning (where furrows go)
⚙️ #Actomyosin + membranes→ mechanical ingression (how furrows grow)
Disrupt either one and the process breaks — but in different ways.

At this high resolution, we also caught something new: Using the new #HAK-Actin #UExM probe, we saw that
#Actin accumulates at the furrow base before compartments fully seal ➡️ they're still open at the bottom.
➡️ The #multicellular epithelium-like stage is shorter than we previously proposed.

Using #UExM, we could finally see the MT network. Two populations:
Cortical MTs=from MTOCs to the cortex, spacing nuclei evenly
Furrow-tracking MTs=elongating with the ingressing membrane.

We knew from previous work MTs weren't strictly required for #cellularization ! PM furrows still form without them,but things go wrong.
Turns out MTs are essential for spatial fidelity: without them, furrows misdirect, nuclear spacing goes haywire, and dynamics is slower!
