Journal stemceller's Journal: Scientists discover protein cue that allows limb regrowth in newts

Agence France Presse (AFP) reports "Scientists have discovered a protein's molecular signal that apparently plays a key role in allowing newts -- which are amphibians -- to regrow severed limbs, a report in the journal Science said Friday. The protein called nAG, produced by nerve and skin cells, apparently plays a key role in stimulating blastema cells, the undifferentiated cells from which a new organ or limb can grow, Kumar and colleagues at University College London and A.A. Garza-Garcia at the National Institute for Medical Research in London found."
