Cell-Based Therapies: Strategies for Regeneration.

Abstract

The neural retina of mammals, like most of the rest of the central nervous system, does not regenerate new neurons after they are lost through damage or disease. The ability of nonmammalian vertebrates, like fish and amphibians, is remarkable, and lessons learned over the last 20 years have revealed some of the mechanisms underlying this potential. This knowledge has recently been applied to mammals to develop methods that can stimulate regeneration in mice. In this review, we highlight the progress in this area, and propose a "wish list" of how the clinical implementation of regenerative strategies could be applicable to various human retinal diseases.
