Figure 3. Neurofilament light chain (NFL) and glial fibrillary acidic protein (GFAP) expression in transplanted retinal progenitor cells (RPCs). Retinal sections from wild-type, noninjected, and injected eyes were immunostained with anti-NFL (A-C) and anti-GFAP (G-I) antibodies (red). Dashed boxes indicate regions depicted at higher magnification in panels D-F and J-L. Sections were counterstained with DAPI. Scale bars: A-C and G-I: 100 μm; D-F and J-L: 50 μm.
