總結
Salamanders, particularly axolotls, can regenerate limbs, heart, and brain tissue through a process involving dedifferentiation of cells and formation of a blastema. This allows them to regrow lost limbs without scarring. Research continues to explore the mechanisms behind this regeneration and its potential applications for other species, including humans.
