But this eye is by no means as developed as the organ of vision, for instance, of the water salamander (the triton) or of the so-called axolotl, for it exists only in a kind of embryonic development, and contains neither a vitreous humor nor a lens for the refraction of the rays of light.
Among the world's varied creatures, a Mexican salamander called the axolotl appears best at regrowing whole limbs lost to injury.
"The axolotl is the champion of vertebrate regeneration, with the ability to replace whole limbs and even parts of its central nervous system," says Edward Scott, Ph. D., principal investigator for the grant and director of the McKnight Brain Institute's program in stem cell biology and regenerative medicine.
"The axolotl is the highest, most complex organism that can still do this clever trick of completely reconstructing a whole body part in adulthood," said Arlene Chiu, Ph. D., a scientific adviser for the Regeneration Project and director of New Research Initiatives at Beckman Research Institute of the City of Hope.
"The axolotl is the champion of vertebrate regeneration, with the ability to replace whole limbs and even parts of its central nervous system," Scott said.
Limb regeneration in the axolotl occurs when undifferentiated cells accumulate under the wound epidermis at the amputation site, a process known as the establishment of a blastema.
