We just released a new major version of TrackMate (v8), the cell and organelle tracking plugin of Fiji.
It ships many new features, detailed below, but that are articulated around the following:

The lab’s first pre-print! We investigated how growth-inducing Erk activity waves are regulated in regenerating zebrafish scales. We discovered that Erk waves are followed by waves of expression of their own inhibitors, as predicted by excitable waves theory. tinyurl.com/26r2cmpj

Why would Mycobacterium shed its surface right after entering a host cell? Host phagocytes rapidly strip its outer layer, releasing components that alert neighbors and trigger defense responses
Our preprint is out, curious to hear your take! 👀

Ectopic head regeneration after nervous system ablation in a sea anemone
Via genetic ablation of neurons, Mazloumi Gavgani et al. show that the nervous system
is essential for defining axial polarity during whole-body regeneration in the sea
anemone Nematostella vectensis.

Hi, I’m David Brückner @davidbrueckner.bsky.social.
I’ll take you through how cells in a tissue can use information distributed by biochemical gradients to make decisions, and how we can measure such positional information.

Signal control during tissue regeneration in adult animals
Nature Reviews Molecular Cell Biology, Published online: 11 November 2025; doi:10.1038/s41580-025-00917-1The ability to track single cells in vivo, combined with insights into chromatin structure, immune–tissue crosstalk, bioelectric and metabolic cues and quantitative modelling, is changing our understanding of how tissues are repaired and renewed. This Review discusses how signals are regulated during regeneration and future directions for a more quantitative understanding of regenerative biology.
