Axolotl Regeneration: Cracking the Code for Limb Regeneration
2025-06-20
Scientists have identified retinoic acid as a key molecule in the limb regeneration of axolotls, amphibians known for their remarkable regenerative abilities. This molecule forms a gradient across the body, guiding regenerating cells to rebuild the correct tissues in the right places. Experiments showed that increasing retinoic acid levels caused axolotls to regenerate entire limbs, rather than just the missing part. This research offers a promising avenue for human limb regeneration, suggesting that we might one day be able to regenerate injured tissues and organs like axolotls.
