Static morphogen scaling enables proportional growth in a tissue growth model inspired by axolotl limb regeneration

Proceedings of the National Academy of Sciences, Volume 122, Issue 47, November 2025. SignificanceRegeneration of lost body parts must not just recapitulate developmental programs, but also adjust to the size of the adult organism. The control mechanisms enabling such size-adaptive morphogenesis are not well understood. Here, we propose a …
