Fig. 5. ISL1 and BRN3B regulate the expression of a common set of RGC-specific
genes. (A-H) Compared with controls (left panels), in situ
hybridization shows that at E14.5, the expression of RGC-specific genes
Brn3a, Isl2, Olf1, Irx4, Ablim1, Gap43, L1cam and Shh
decreases in the GCL (bracket) of both Isl1-null (middle panels) and
Brn3b-null retinas (right panels). T, temporal; N, nasal. Scale bar:
100 µm.
