Fig 1. Expression of nol11 during vertebrate development.
A) Wild type nol11 expression pattern during Xenopus tropicalis development. Note the strong expression in developing neural folds (NF) and the presumptive CNC at stages 16 and 22 (lateral [left] and dorsal [right] views presented). Expression is strongly associated with the migrating and differentiating CNC at subsequent stages, and is also detected in the region of the ventral blood islands (BI) and isthmus (Is) at stage 28. BA, branchial arch; Ht, heart; Lv, liver region; Op, optic placode. B) and C) Anterior transverse dissections showing expression of nol11 in neural folds and premigratory CNC of stage 14 and 16 embryos respectively. Plane of dissection is represented by the red dotted line marked c in A. D) Horizontal dissection (shown as dotted red line marked d in A) of nol11 expression in the branchial arches of stage 28 Xenopus embryos. E) nol11 expression in E8.5, E9.5 and E10.5 wild type mouse embryos. At E8.5 expression is strongly detected in the neural folds. Transcripts are associated with CNC positive regions at both E9.5 and E10.5. BA2, 2nd branchial arch; FNP, frontonasal prominence; Ht, heart; mdBA1, mandibular BA1; mxBA1, maxillary BA1; Op, optic placode; Ot, otic placode; T, trigeminal region.

S4 Fig. Rates of cell death in the branchial arches.
A) Graph of the number of Tunel positive cells per 100 cells present in sections of the branchial arch region of stage 28 UC, CMO, Nol11 MO, Nol11 MO + p53 MO, and p53 MO only injected embryos (* = P < 0.05). B) Whole mount stage 28 embryo with plane of section represented by the red dotted line. Representative Tunel stained (green) sections from each control and morphants.
