How Do Axolotls Regrow Limbs?

💡 The Answer

• Axolotls can regenerate entire limbs, spinal cord, and even parts of their brain without scarring.
• Their cells dedifferentiate into a stem-like state, then differentiate into the required tissue types.
• The process reactivates complex signaling pathways normally active only during embryonic development.
• Scientists study axolotls to understand regenerative medicine and potential applications in human health.
