Phox2b deficiency causes arrest of SCG cells at an undifferentiated stage.

(A,B) Dorsal views of ISH with FITC-labeled th (red) and digoxigenin-labeled phox2b (blue) riboprobes on 4-dpf embryos in which phox2b expression was abrogated by MO knockdown. Arrows point to the SCG. Insets show enlarged views of the SCG. (C, D) Lateral views of ISH with FITC-labeled phox2b (red) and digoxigenin-labeled dbh (blue) riboprobes in MO-injected (D) and control (C) embryos. (E) Quantitative real time-PCR analysis comparing phox2b mRNA expression levels in control vs. phox2b MO-injected (P2BATG MO) embryos. Data are presented as means ± SD (^****P<0.0001, ^***P<0.001; n = 15 per group). (F,G) Whole-mount ISH for elavl3 in the area of the SCG (arrow) in phox2b MO-injected (G) compared to control MO-injected embryos at 4-dpf (F). (H–K) Lateral views of the SCG in 4-dpf embryos overexpressing the indicated RNAs analyzed for elavl3 expression by whole-mount ISH.
