Figure 1. Postnatal Müller-derived progenitors express nestin and NR1. A: Photomicrograph shows cultured Müller-derived progenitors labeled with an antibody against nestin (red) and counterstained
with DAPI (blue). B-D: Photomicrographs show cultured Müller-derived progenitors double-labeled with antibodies against NR1 (B), nestin (C), and overlay (D). Arrow indicates nestin immunopositive and NR1 inmmunonegative-labeled cells. Bar in each panel equals 50 μm.
