Effects of exogenous RA on eye dorsoventral (DV) polarity. (A and B) Lateral views of heads of 25 to 26 hpf embryos treated with DMSO or 0.25 μM RA from 3s and hybridized with the indicated probes. RA treatment up-regulates pax2, but not vax1, net1a, vax2, or aldh1A3 expression in the dorsal eye. Arrowheads point to expression in the VR/OS. RA treatment causes no evident effects on tbx5 expression in the dorsal eye (triangles).
