Newts and salamanders have long been known for their capability to renew damaged body parts. Scientists have now identified a protein playing the significant role in this process of regeneration. Researchers working at the University College London (UCL) identified that a protein called nAG is important for the production of blastema cells, which regrow the missing body part. The protein is secreted by nerve and skin cells, and proposed to hold importance for regenerative medicine. The scientists of the research group which discovered this key protein said that the results of the study “may hold promise for future efforts to promote limb regeneration in mammals”.
