An axolotl, or Mexican salamander (IMAGE) MDI Biological Laboratory Caption Prayag Murawala, Ph.D., of the MDI Biological Laboratory in Bar Harbor, Maine, uses the axolotl, or Mexican salamander, to study tendon regeneration. The axolotl is considered nature's champion of regeneration because of its ability to regenerate almost any body part, including, in addition to tendon tissue, limb, heart, brain, eye and spinal cord. He is exploring why the axolotl is capable of such remarkable feats of regeneration while humans are not.
