RA signaling negatively regulates dact3b expression. (A, D) Control embryos. (B, E) Treatment with exogenous RA extinguishes dact3b expression in the hindbrain (black arrows) and second pharyngeal arch (white arrow in E). (C, F) Inhibition of RA signaling lead to an expansion of dact3b expression domain with the hindbrain (compare the length between arrows in D and F). Images are lateral views with anterior to upward.
