Salamanders are pretty awesome. They can regenerate limbs that have been lost, and they’re able to heal body parts even after pretty significant damage. So it’s not a stretch to think that these small amphibians are providing some inspiration for the next generation of wound healing therapies in humans.
Researchers discovered a peptide in salamander skin called tylotoin that promotes wound healing. In laboratory studies, this peptide also promoted wound healing in mice with skin wounds. Tylotoin works by increasing the motility and production of certain types of cells, and as a result, skin cell regeneration and tissue formation around the wound occur more quickly.
Pretty amazing! And this type of research illustrates the importance of animal models in several different ways. Researchers were able to isolate this specific protein from the salamander AND prove its effectiveness on the mouse. Hopefully, unlocking the salamander’s secrets will also be able to help humans recover from injuries more quickly. Read more about it here:
