Collective cell motion has many forms, but rotation is the coolest of them all.

I'm @onenimesa.bsky.social , and in this short🧵, I'll highlight some instances of global tissue rotation like this one from @BauschLab

FINALLY out in #Science Advances! 🎉
3 years of hard work, a fantastic team — and I’m proud to be first and co-corresponding author!

It's about Plexin signaling driving collective cell migration & organ sculpting. Check out the videos 😀

What do we see when looking at cells under the microscope? 👉Some are bigger than others, some are elongated and align with the neighbors & others seem to move. Cool, right? But wouldn't it be cooler to quantify these observations?

I'm @juliaeckert.bsky.social. Let's explore some analysis software!‬

The tip of the cantilever consists of a fluorescent bead that contacts the epiblast. Because we know the force necessary to bend the cantilever, we can perform mechanical assays by driving the bead across the embryo and measure in real time the force applied to the tissue.

Collective cell migration is fascinating!
Some tissues behave like fluids (motile), others like solids (jammed).

Check out some papers exploring this topic in this thread.

Trichoplax adhaerens is one of the simplest and most enigmatic animals on earth. Its body shows incredible fluidity, changing shape within minutes. In a recent visit by Andrea Pasini we had the chance to host and observe these amazing animals live.

This movie was taken by Shinya Inuoe, who built the polarizing microscope that allowed scientists to see mitotic spindle fibers live for the first time.
