Axolotls can regenerate new limbs, tails, and even heart and brain cells, making them a research opportunity for long-term human health.
Perhaps the most impressive aspect of the axolotl’s biology is its power of regeneration. Not only can it reproduce a new limb or tail when these have been lost by accident or through attack by a predator, the axolotl can also regenerate brain and heart cells, characteristics that have made it a focus of a considerable amount of research with a long-term application for human health.
Axolotls are an important research animal and have been used in studies of the regulation of gene expression, embryology, neurobiology, and regeneration. They are one of the most widely used and studied laboratory animals.
