Mapping limb regeneration is an intricate, molecular dance. If an axolotl loses a leg, it gets a new one–complete with a functional foot and all four toes. Over just a few weeks or months, bone, ...

Some animals in the world possess the ability to regenerate tissues, allowing them to regrow parts of limbs or entire limbs after amputation. In a study published in the journal PNAS, a ...

Hierarchical communication between cells with distinct positional memories orchestrates the regeneration of missing limb structures in axolotls.

When humans lose a limb due to an injury, there are lifelong lifestyle changes that are necessary to accommodate the loss of the arm or leg. In some instances, the changes are minor, with people ...

Although often glossed over, the human liver is a pretty amazing organ. Not just because it’s pretty much the sole thing that prevents our food from killing us, but also because it’s the only organ in ...

A tiny creature with frilly gills, a polite smile and glowing green skin just gave scientists a major clue to solve one of biology’s biggest mysteries: limb regeneration. Aquatic salamanders called ...

Axolotl limbs regenerate functional body parts in just weeks, relying on cells that retain positional memory. A study led by Elly Tanaka’s team at IMBA reveals that the Hand2 gene marks the posterior ...

Recent research into limb regeneration in amphibians has revealed a sophisticated orchestration of molecular and cellular events that enable these species to restore lost appendages. At the centre of ...

Many lower organisms retain the miraculous ability to regenerate form and function of almost any tissue after injury. Humans share many of our genes with these organisms, but our capacity for ...
