Mechanisms of retina regeneration in urodeles

This review is a comparative analysis of retina regeneration in amphibians, fish, birds, and mammals. Special attention is given to the newt, which, unlike other vertebrates, retains the capacity for the regeneration of eye structures during all life. The review focuses on the sources of the cells which contribute to retina regeneration, the factors which control the process, and the genes expressed during the course of regeneration.
