Washington, Nov 19: Researchers at the Salk Institute for Biological Studies have successfully regenerated a wing in a chick embryo, a species not known to be able to regrow limbs.
Their experiment suggests that the potential for such regeneration exists innately in all vertebrates, including humans.
The study published in the online edition of Genes and Development demonstrates that vertebrate regeneration is under the control of the powerful Wnt signalling system.
