Retinal stem cells in vertebrates

Summary
In fish and amphibia, retinal stem cells located in the
periphery of the retina, the ciliary marginal zone (CMZ),
produce new neurons in the retina throughout life. In
these species, the retina grows to keep pace with the

proportions, however, their retinas stop growing so
there appears to be no need for such a proliferative area
