Schematic of limb regeneration in axolotl, with growth controlled by two oppositely oriented morphogen gradients (SHH, FGF8).

Axolotl can regrow lost limbs, matching their body size. How? Our new theory-experiment paper in @pnas.org proposes how oppositely oriented morphogen gradients scaling with animal size promote proportional growth. Great collaboration with @tatianasg.bsky.social @cmcb-tud.bsky.social
