Fig. 7 Reduced dlx2a expression in pharyngeal arches 3–4 in pax1a; pax1b morphants beginning at 22 hpf. Similar dlx2a expression levels were detected in three migrating streams (S1, S2, S3) of cranial neural crest cells in uninjected (C), 0.75 ng pax1a MO-injected pax1b−/− mutant embryos (D), uninjected wild types (WT; A) or 0.75 ng pax1a MO-injected wild types (B) during 18–22 s stages. Similar dlx2a expression levels in three migrating streams of cranial neural crest cells were observed in wild types and pax1a; pax1b morphants at 18 hpf (E, L) and 20 hpf (F, M). However, reduced dlx2a expression (asterisk) was identified in pharyngeal arches (pa) 3–4 of pax1a; pax1b morphants compared to wild-type embryos at 22 hpf (G, N), 24 hpf (H, O), 26 hpf (I, P), 28 hpf (J, Q) and 30 hpf (K, R). Scale bars represent 100 μm.
