Fig. 6. Neurod1 and Math3 activate the RGC gene regulatory network in the
absence of Math5. Math5Neurod1-KI/Math3-KI retinas
from E14.5 (or E13.5 for G1,G2) embryos were analyzed by in situ hybridization
(purple) or immunostaining (green). (A1-H1) Wild-type retinas.
(A2-H2) Math5Neurod1-KI/Math3-KI retinas. In situ
hybridization probes and antibodies for immunostaining representing genes
downstream of Math5 are indicated in the lower left-hand corner in A1-H1.
