Salamanders (A. mexicanum) regenerate spinal cords with roof plate-associated structures, while lizards (L. lugubris) do not. When an organism is wounded, its cells are activated and the damaged tissues and organs are remodelled back to the original state. Many of them are also animated. The plasticity of differentiated cells is a notable feature in different contexts of non-neural regeneration in salamanders, but this term encompasses a range of phenomena . During salamander limb regeneration, an early down-regulation of p53 is a prerequisite for mesenchymal cell dedifferentiation and blastema formation (Yun et al.

Epimorphosis can be considered a simple model for development, though it only occurs in tissues surrounding the site of injury rather than occurring system-wide. Photo by MTSOfan. This process is still not fully understood and could still take many years to truly see how it works. The salamander is a superhero of regeneration, able to replace lost limbs, damaged lungs, sliced spinal cord -- even bits of lopped-off brain. Regeneration process begin Immediately after amputation.

Purpose of the study ... All performed at Princess Margaret Hospital. During tail regeneration, they all turn on genes in what is called the 'Wnt pathway’ – a process that is required to control stem cells in many organs, such as the brain, hair follicles and blood vessels. It’s similar to what happens in a developing embryo, but unique to regeneration are signaling from nerves and cells’ ability to morph into new types. While there are still many exciting areas to explore in salamander limb regeneration, it is a question that is firmly in an age of molecular insights linked to conceptual understanding.
