Meet the axolotl, a rare and fascinating salamander that breaks all the rules of nature. With its perpetual smile and ...

A better understanding of how these amphibians grow new appendages may lead to better wound healing—or even new limbs—in humans.

A new study reveals the key lies not in the production of a regrowth molecule, but in that molecule's controlled destruction.

“We discovered it’s essentially a single enzyme called CYP26b1, that regulates the amount of tissue that regenerates,” Monaghan says. CYP26b1 breaks down retinoic acid, so when the gene that makes the ...

Molecular signals after severing an axolotl arm direct the remaining cells how to regrow the limb, offering potential ...

The adorable salamanders are helping scientists investigate a serious question: Could the human body be coaxed to regrow a ...

Could humans be capable of growing new limbs? Scientists are trying to figure that out with the aid of an unexpected resource: salamanders. Research shows that the amphibians' regeneration abilities ...

Axolotls are the gold medallists when it comes to limb regeneration. Researchers from Northeastern University have discovered ...

In other words, an injured axolotl hand knows not to grow into an arm partly because the enzyme, called CYP26B1, blocks the regeneration process from going further, McCusker explained.
