Breakthrough Understanding of Limb and Organ Regeneration – Closer to the Development of Regenerative Medicine Therapies
Discovery in Salamanders by James W. Godwin, Ph.D., brings science closer to the development of regenerative medicine therapies.
Many salamanders can readily regenerate a lost limb, but adult mammals, including humans, cannot. Why this is the case is a scientific mystery that has fascinated observers of the natural world for thousands of years.
Now, a team of scientists led by James Godwin, Ph.D., of the MDI Biological Laboratory in Bar Harbor, Maine, has come a step closer to unraveling that mystery with the discovery of differences in molecular signaling that promote regeneration in the axolotl, a highly regenerative salamander, while blocking it in the adult mouse, which is a mammal with limited regenerative ability.
“Scientists at the MDI Biological Laboratory have been relying on comparative biology to gain insights into human health since its founding in 1898,” said Hermann Haller, M.D., the institution’s president. “The discoveries enabled by James Godwin’s comparative studies in the axolotl and mouse are proof that the idea of learning from nature is as valid today as it was more than one hundred and twenty years …
