PTU at high concentrations inhibits neural crest development.

96 hpf roy Tg(fli1::EGFP) and roy Tg(sox10::EGFP) embryos were treated with 0.003% (A–H) or 0.03% (I–P) PTU at 6 hpf or 22 hpf. Treatment with 0.003% PTU at 6 (A–D) or 22 (E–H) hpf inhibited pigmentation (A, E) but did not affect development of the retinal-hyaloid vasculature (B, F), pharyngeal arches (PA; C, G), and jaw cartilage (D, H) as compared to untreated embryos (Q–T). At a concentration of 0.03%, PTU at 6 hpf inhibited neural crest development (I–L) including pharyngeal arch development (K), jaw formation (L), and the remodeling of the hyaloid vessel into the hyaloids retinal plexus (J). Treatment with 0.03% PTU at 22 hpf caused pharyngeal arch (O) and jaw malformation (M, P), but did not affect the hyaloid-retinal vasculature (N).
