Unraveling the mechanisms behind organ regeneration in zebrafish
The search for the holy grail of regenerative medicine -- the ability to "grow back" a perfect body part when one is lost to injury or disease -- has been under way for years, yet the steps involved in this ...

Zebrafish regrow fins using multiple cell types, not identical stem cells
What does it take to regenerate a limb? Biologists have long thought that organ regeneration in animals like zebrafish and salamanders involved stem cells that can generate any tissue in the body. But new ...

A master mechanism for regeneration?
ANN ARBOR, Mich.---Biologists long have marveled at the ability of some animals to re-grow lost body parts. Newts, for example, can lose a leg and grow a new one identical to the original. Zebrafish can re-grow fins.
