Experiments show how mechanical forces influence morphology during tissue regeneration in #Hydra. When the animal is constrained into a narrow channel, it can develop a multiaxial body plan — including multiple heads. Read the paper: https://t.co/oITfzXkPjZ

But that is not all! How is this regeneration process affected by mechanical confinement? https://t.co/INC2HiSgt1
biorxiv.org
The establishment of the body plan is a major step in animal morphogenesis. The role of mechanical forces and feedback in patterning the body plan remains unclear. Here we explore this question, by...

Our work on random traction yielding transition in epithelial tissues is finally published! @mpi_pks @AboutalebAmiri , Charlie Duclut, Frank Julicher https://t.co/7vEHd1n7xU
journals.aps.org
We investigate how randomly oriented cell traction forces lead to fluidization in a vertex model of epithelial tissues. We find that the fluidization occurs at a critical value of the traction force...
