Blastema

The mass of undifferentiated cells that forms at the wound of a regeneration-capable animal — like the axolotl — and regrows an entire, complete limb from scratch. The blastema must proliferate, pattern, and differentiate in sequence, taking weeks to months, and in vertebrates it only works when nerves are present. This kinetic limit is exactly the wall between real regeneration and cinematic "instant regrowth."
