Thrilled to share this adventure on how zebrafish elongates its notochord! 🐟 Kudos to Carlos Camacho de la Macorra and @BenSteventon2 for leading it. @CeccarelliAS and I had so much fun modelling & uncovering unexpected predictions...

Stay tuned for more upcoming projects 😉!

I would like to thank all my amazing colleagues @borgesaugust, @hey_jero, @CeccarelliAS, @gbventur, @ksedzinski, and @LopezSchier365, as well as the reviewers, the editorial team of @iScience_CP and the community for their support.

We’re also grateful to the Editor and Reviewers for their helpful feedback. We hope this study contributes to a deeper understanding of how cells regain their place in a regenerating organ.
Thanks for reading! 🙌

This work was made possible by a stellar team: Hernan Arce (PhD), @CeccarelliAS (postdoc), @RepreARG (Diploma student) from my lab and our collaborators Catarina Oliveira, and @MaxYunLab . Huge thanks to all!

Cells in a regenerating axolotl limb somehow know their place—but how?
In our new paper, we trace the dynamics of positional memory, release open-source code to quantify it, and introduce a theoretical framework for proximalisation.

🔬Curious about how to achieve an organ-wide regenerative response through locally controlled cell proliferation? Check out our latest preprint, which computationally addresses this problem in the neuromast within the zebrafish lateral line.

Our new adventure on how Shh+ floor plate cells contribute to spinal cord regeneration along the dorsal-ventral axis in our beloved axolotl is now ready for you! The heroes of this story are my amazing colleagues and friends @lauraarbanas, @LeoOtsuki, @CuraCosta and @Tanaxolotl!!

[Osvaldo Chara @Osvaldo_Chara]

The great @CeccarelliAS starts his position in our group! Welcome Alberto! Here we have one with our collaborator and friend @AlberioRamiro!

[Osvaldo Chara @Osvaldo_Chara]

We present ForSys, a new method to portray the mechanical state of a tissue in space and time!!

[Augusto @borgesaugust]

Our software, ForSys, is finally out as a preprint! I am thrilled to have worked on this fantastic story. I want to thank @hey_jero, @CeccarelliAS, @gbventur, @ksedzinski, Hernán López-Schier, and @Osvaldo_Chara for this amazing journey. Stay tuned for more!

[Osvaldo Chara @Osvaldo_Chara]

In between the dynamical phases of #tissue growth and decay the tissues are in #homeostasis, which we showed that can be considered a state of #criticality.

[Osvaldo Chara @Osvaldo_Chara]

Would you like to know if spinal cord regeneration in the axolotl could be explained by a Reaction-Diffusion signal? If yes, check out our new adventure: https://t.co/2yeURkQh0i #bioRxiv

[Osvaldo Chara @Osvaldo_Chara]

Is critical a tissue during homeostasis?
Can a toy Markovian model describing the cells as (stupid) entities that don't "remember" where they are in the cell cycle actually represent a non-Markovian model of tissue growth? Check out our last adventure in bioRxiv!
