TS13: neural crest	neural crest cell	Present	Regionally restricted	1B	Expression was detected in premigratory and migratory cranial neural crest cells.
TS13: migrating neural crest	migratory neural crest cell	Present	Regionally restricted	1B	Expression was detected in migratory cranial neural crest cells.

Structure	Cell Type	Level	Pattern	Image	Note
TS15: migrating neural crest	migratory neural crest cell	Weak	Regionally restricted	1D , 1E	Low level expression was detected in trunk neural crest cells as they emigrate from the neural tube.

Structure	Level	Pattern	Image	Note
TS20: dorsal root ganglion	Present		1F	At 12.5 dpc Foxd3 and Sox2 are co-expressed in the dorsal root ganglion.

Structure	Level	Pattern	Image	Note
TS21: vibrissa dermal component	Present		2C , 2A , 2B	At 12.5 dpc, expression was detected in the dermal condensates. Co-expression with Foxd3 was observed.

Structure	Level	Pattern	Image	Note
TS25: vibrissa dermal papilla	Present		2E , 2G , 2F	Expression was detected in the neural crest lineage in the dermal papilla. Co-expression with Foxd3 was observed.
TS25: vibrissa follicle	Present	Regionally restricted	2E , 2G , 2F	Expression was detected in the non-neural crest lineage in the more proximal part of the whisker follicle. This expression domain did not co-label with Foxd3.

Structure	Level	Pattern	Image	Note
TS24: dorsal root ganglion	Present		4C

Structure	Level	Pattern	Image	Note
TS24: dorsal root ganglion	Absent		4D

Structure	Level	Pattern	Image	Note
TS25: vibrissa follicle	Present	Regionally restricted	5C , 5A , 5B	Expression was detected in the neural crest lineage domain, where it overlapped with Foxd3, and in a domain outside the neural crest lineage.

Structure	Level	Pattern	Image	Note
TS25: vibrissa follicle	Present	Regionally restricted	5E , 5G , 5F	Expression was lost in the neural crest lineage in the mutant. The non-neural crest lineage expression was unchanged in the mutant.
