Figure 1.

Retinal expression of CFP and ChAT in Thy-1 (CFP) control retinas. (A) ChAT(+) immunostaining. ChAT(+) cells (red) are present in both the RGC and INL layers (1A, arrows). There are two ChAT(+) synaptic layers within the IPL (arrowheads). (B) Retinal CFP expression in a control retina cross-section. Cellular CFP (green) expression is limited to the RGC layer. (C) Merged images. There is little overlap of cells strongly expressing both labels. OPL, outer plexiform layer; ONL, outer nuclear layer. Scale bar, 100 μm.
