Axolotl Limb Blastema — 2D Regeneration Profile

This 2D companion to the 3D axolotl blastema simulator drives the identical verified FGF/Wnt/BMP logistic-growth model, but lays the whole proximodistal limb axis out as a single pannable, zoomable strip instead of a rotating 3D mesh. Amputate at three different levels and watch wound fibroblasts dedifferentiate into a blastema, its size and speed governed by FGF, Wnt/β-catenin and BMP signalling, while a live graph beneath the limb view plots blastema cell count and percentage of limb length regenerated across the whole timeline — so the logistic growth curve and the outgrowth curve are visible at once, not just their instantaneous values.
