Figure 2. Cell-type specificity of Cre recombinase activity in mouse lines with different IRES-CreER knock-ins.

Figure 2

The cell-type specificity of each line was tested by crossing to the Z/AP reporter and inducing sparse recombination with 4HT. A, In the retina, the NFL-IRES-CreER line exhibits Cre-mediated recombination in retinal ganglion cells, each of which has a single axon projecting to the optic disc, and in horizontal cells; the image shown here shows only retinal ganglion cells. B, in the brain, the VAMP2-IRES-CreER line exhibits Cre-mediated recombination in both neurons and glia. C and D, in the retina, the ChAT-IRES-CreER line exhibits Cre-mediated recombination exclusively in cholinergic (starburst) amacrine cells. The region boxed in C is shown at higher magnification in D. Scale bars: 0.5 mm in A and B; 1 mm in C.
