Characterization of Muller glia and neuronal progenitors during adult zebrafish retinal regeneration.

ABSTRACT: The adult zebrafish retina exhibits a robust regenerative response following light-induced photoreceptor cell death. This response is initiated by the Müller glia proliferating in the inner nuclear layer (INL), which gives rise to neuronal progenitor cells that continue to divide and migrate to the outer nuclear layer (ONL), where they differentiate into rod and cone photoreceptors. We previously conducted a microarray analysis of retinal gene expression at 16, 31, 51, 68, and 96 h of constant intense-light treatment to identify genes and their corresponding proteins that may be involved in the generation and proliferation of the neuronal progenitor cells. We examined the expression of two candidate transcription factors, Pax6 and Ngn1, and one candidate transgene, olig2:EGFP, in the regen
