 Studies to this end of Müller glia in both the zebrafish and chicken retina have been performed, with the exact molecular mechanism of regeneration remaining unclear.Further studies performed in mice have shown that overexpression of Ascl1 in Müller glia in conjunction with administration of a histone deacteylase inhibitor allowed for regeneration of retinal neurons from Müller glia.Studies in human models have demonstrated that Müller glia have the potential to serve as stem cells in the adult retina and are efficient rod photoreceptor progenitors.
