Rediscovering the Axolotl as a Model for Thyroid Hormone Dependent Development

open access: yesFrontiers in Endocrinology, 2019
The Mexican axolotl (Ambystoma mexicanum) is an important model organism in biomedical research. Much current attention is focused on the axolotl's amazing ability to regenerate tissues and whole organs after injury. However, not forgotten is the axolotl'
