Figure 1. Math5-Cre reporter mice. Confocal fluorescence microscopy image of a retinal flat mount from an animal derived from crossing ROSA26
green fluorescent protein-reporter mice with math5-Cre mice. Note the presence of green fluorescence protein (GFP) in the retinal ganglion cell axons and some underlying soma
in the ganglion cell layer, reflecting the presence of math5-Cre in these cells, but the lack of math5-Cre expression in retinal vascular cells (red). Scale bar=100 µm.
