Sparse mesenchymal cell networks as a fluid under tension Sparse mesenchymal cellular networks are ubiquitous across animals, shaping both embryonic and adult structures through dynamic interactions with epithelia. Yet, the physical principles underlying the...

How do sparse mesenchymal cells, with unique stellate arms spanning large gaps between cells, maintain their network while still flowing during development? In our new preprint we describe the avian PSM as a fluid under tension and develop new theory to explain it: www.biorxiv.org/content/10.6...

Fascinating work on the biomechanics of mesenchymal tissues right here:

One for #NeuralTube biologists:

To mark Black Friday, we are excited to share our latest work, "Planar polarized force propagation integrates cell behavior with tissue shaping during convergent extension." Now online in Current Biology. authors.elsevier.com/a/1kATd3QW8S...

Congrats to Fernanda - she really came up with some really creative solutions to our questions!

Happy to share our new preprint with Vernanda Perez-Verdugo, @shilabanerjee.bsky.social @glgalea.bsky.social We show that mechanical feedback drives shape and spatial order of the surface ectoderm in hindbrain neuropore closure.

How do physical forces influence spatiotemporal cell patterning during tissue morphogenesis? Our latest preprint integrates theoretical modeling with live imaging of mouse embryos to reveal how mechanosensitive feedback drives self-organized cell patterning during hindbrain neuropore morphogenesis.
