Some amphibians — such as salamanders — are famous for their superhero - like ability to regenerate heart, brain, spinal cord, tail and even whole limb tissue throughout their life. (mdibl.org)
Although organ and spinal cord regeneration are clinically important and worthy of intense research investment, regrowing whole limbs provides a flagship example of perfect regeneration in the salamander. (mdibl.org)
We may be some way off from the dream of replacing whole limbs in humans but recent progress confirms that by deepening our understanding of stem cell activation, we can directly unlock more regeneration in mammals than normally possible. (mdibl.org)
