Cell migration and art are two guiding forces in my life 🔬🐸🌈

Collectivity is not uniformity—it’s the coordination of forces under tension. In Xenopus neural crest epithelial clusters, movement emerges from within. From my postdoctoral research: nuclei (red), membranes (magenta), cytoskeleton (green). No internal tension, no collective motion. Tension holds 🐸🔬

Collective migration is not just about leaders at the front, but about coordination across the group.
Always exciting to see these dynamics visualized.
Many thanks to @jcb.org for featuring our work 🐸🔬🌹
So proud to share my paper on collective chemotaxis and force coordination in epithelial and mesenchymal cells, developed in the Mayor Lab and now published in JCB. Deeply grateful for everything I learned from Xenopus NC and the amphibian world, where adaptation is everything🐸
Honored to see our work featured in a JCB Spotlight by Pacheco and @drericabiophd.bsky.social (@UCSF).
The piece discusses our study revealing distinct force-generating mechanisms in epithelial and mesenchymal collective migration
🔬🐸 Thank you for your careful review of our work!

Very happy to share our new paper, where I am first author, developed at University of Chile.
Astrocytes were long overlooked as passive “support” cells, yet they play key roles in brain responses.
We explore how neuroinflammation alters astrocyte behaviour.

Mesenchymal and Epithelial-like Xenopus Neural Crest clusters use distinct force architectures to achieve comparable chemotactic performance

Diaz and @mayorlab.bsky.social show that epithelial and mesenchymal cells navigate chemical cues via fundamentally different force-generating mechanisms, offering new insight into how diverse cell types achieve collective movement during development and disease. rupress.org/jcb/article/...

Background Neuroinflammation induces astrogliosis, a process marked by astrocyte hypertrophy, increased migration, and altered protein expression. While these changes involve both up- and downregulati...

A new paper published in @jcb.org by postdoc Jorge Diaz from the Mayor lab at UCL shows that during collective migration, epithelial-like clusters generate traction force mainly through cryptic protrusions at the centre, while mesenchymal clusters do so at their periphery:
