Regeneration Of Life and Limb

Pamela J. Hines

Science, AAAS, Washington, DC 20005, USA

The ability of amphibians to regenerate an amputated limb represents a developmental flexibility largely lost for humans. The regeneration process in amphibians depends on interactions with the nerve supply. Kumar et al. (see the Perspective by Stocum) have now identified a secreted protein growth factor expressed in the nerves and epidermis of newts during limb regeneration that can serve to support regeneration even when the nerve supply is removed.
