Figure 1. Gene expression in dissociated embryonic green fluorescent protein (GFP)-labeled retinal cells. A: GFP expression. B: Trypan blue staining. Arrows point to dead cells. C-I: Immunostaining with antibodies for retinal progenitor cell (RPC) and retinal ganglion cell (RGC) regulatory proteins (brown). The cells were counterstained with methyl green (blue). Scale bars: 100 μm.
