Cut off a salamander's tail and, in a few weeks, a near-perfect replacement grows. Do the same to a lizard and a new tail will regrow, but it won't be the same as the original. By comparing tail regeneration between the two ...

Study finds stem cells in deer antler

A team of researchers in Seoul, Korea have reported finding evidence that deer antlers - unique in that they regenerate annually - contain multipotent stem cells that could be useful for tissue regeneration in veterinary ...

Regenerative powers in the animal kingdom explored

Why can one animal re-grow tissues and recover function after injury, while another animal (such as a human being) cannot? This is a central question of regenerative biology, a field that has captured the imagination of scientists ...
