Supplementary Figure 7: Ectopic expression of Tbr1 in the retina.
From: Tbr1 instructs laminar patterning of retinal ganglion cell dendrites
(a) En face view of Tbr1-misexpressing RGCs showing a variety of dendritic arborization patterns, contrasting with the similarity in laminar restriction shown in Figure 4. Arrowheads mark Tbr1-overexpressing RGCs. Note that XFP-positive cells include Brn3bhigh, Brn3blow and Brn3b-negative types. Scale=50μm. Experiment was repeated independently in two animals with similar results. (b-d) Tbr1 mis-expressing cells in the inner nuclear layer showing robust overexpression of Tbr1. These cells are amacrine cells (Rbpms-negative, AP2-positive). Scale=25μm. Experiment was repeated independently in three animals with similar results.
