Retinal regeneration in amphibians.

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