Images showing Nestin, GFAP, and DAPI staining as green, red, and blue fluorescence, respectively. Following MNU-induced retinal degeneration, marker expression was assessed on days 1, 3, 5, 7, and 21 by Western blotting. Nestin expression in Müller cells progressively increased for 5 days and then decreased thereafter. Image labels: ONL – outer nuclear layer, OPL – outer plexiform layer, INL – inner nuclear layer, IPL – inner plexiform layer. Reproduced with permission from [51].
