Interestingly, invasion later initiates near the regions that were originally sharp, where forces become locally concentrated, suggesting a form of shape memory.
What makes you take the first step out of going in circles?
Sometimes, it’s the time spent going in circles itself!

This review marks 25 years since the original seminal Cell review by Hanahan & Robert Weinberg and its impactful follow up in 2011.

We studied how a ~500-cell spheroid breaks through a stiff matrix to initiate invasion.
The spheroid starts slightly egg-shaped (elongated), but instead of invading right away, it first undergoes a prolonged orbiting phase, during which it becomes nearly spherical. 🧵

Take a look if you are interested in how a living tissue knows how to sculpt itself!

Partial EMT Drives Persistent Collective Migration via Collision Guidance in Heterogeneous Populations https://www.biorxiv.org/content/10.64898/2026.04.07.714519v1
Published online today in Nature Physics - we show how multicellular spheroids round up and orbit, driving a deterministic transition to 3D matrix invasion at predictable locations.
Amazing work from @jiwon-kim.bsky.social, @htjeong.bsky.social and collaborators

Have you ever thought about inflating tissues?
Or maybe quickly deflating those inflated tissues?

Researchers from the @ianywonglab.bsky.social are working toward understanding the dynamics of how tissues develop, as well as how cancer cells break free of tumors to spread around the body, by unpacking how cells interact with each other and their surroundings. www.brown.edu/news/2026-01...
