cdx4 mutants show impaired segmental migration of trunk NC cells. A-C. Lateral view of 24 hpf WT embryo labeled with anti-Sox10 (A, NC cells, magenta) and anti-Myosin Heavy Chain (B, somites, green) antibodies reveal segmental migration pathways of trunk NC cells, scale bar ?= ?100 ??m. A?-C?. High magnification images of boxed area from A-C (arrows ?= ?individual segmental chains), scale bar ?= ?50 ??m. D-F. Lateral view of 24 hpf cdx4ch107?/- embryo labeled with anti-Sox10 (D, NC cells, magenta) and anti-Myosin Heavy Chain (E, somites, green) antibodies reveal defects in trunk NC cell migration. Scale bar ?= ?100 ??m. D?-F?. High magnification images of boxed area from D-F, scale bar ?= ?50 ??m. G. Schematic representing approach for mapping the position of trunk NC cells relative to the adjacent somite; analysis was performed at the level of somites 5?10. H, I. Plots of migrating trunk NC cells relative to the adjacent somite in WT embryos (H) and cdx4ch107?/- embryos (I). Data from 18 total segments were superimposed on each plot.
