Structure	Level	Pattern	Image	Note
TS15: migrating neural crest	Present	Regionally restricted	4A/B	Expression detected in migrating neural crest cells in the regions of rhombomere 2, rhombomere 4, and rhombomeres 6 and 7, separated by rhombomere 3 and rhombomere 5, which release little or no neural crest cells.

Structure	Level	Pattern	Image	Note
TS15: migrating neural crest	Present	Regionally restricted	4C/D	Expression detected in migrating neural crest cells opposite rhombomere-like structures RII and RIV-V, which are separated by a crest-cell-free RIII.
