Fig. S4 lsn mutants have no defect in the migration and initial differentiation of pharyngeal cartilage neural crest or in initial specification of the thymus.(A, B) Lateral view of dlx2a expression in the migrating neural crest of wild-type (A) and lsn (B) embryos at 36 hpf. (C, D) Ventral views of pax9 expression in the differentiating pharyngeal arch neural crest of wild-type (C) and lsn (D) embryos at 48 hpf. (E, F) Lateral view of foxn1 expression in the thymic primordium of wild-type (E) and lsn (F) embryos at 48 hpf. ot, otic vesicle; b, branchial arches; h, hyoid arch; m, mandibular arch. Arrows in E,F indicate foxn1 expression.
