When newts lose a leg, they regenerate a new one. Even destroyed cardiac tissue is swiftly replaced by healthy tissue. What is the underlying mechanism?
Newts and salamanders have the unique attribute to fully regenerate lost limbs. Not only lost legs, also eye lenses, the jaw, parts of the central nervous system and even cardiac tissue are fully restored.
Scientists at the Max-Planck Institute for Cardiac and Pulmonary Research in Bad Nauheim, Germany, have been working intensively for years on the mechanisms underlying this phenomenal regenerative capacity.
