TS17: 4th branchial groove	Present		1A
TS17: otocyst	Present		1A
TS17: embryo	Present	Regionally restricted	1A	Expression is detected in putative migrating cranial crest cells (located between the forebrain-midbrain junction and the eye, at the level of the midbrain-hindbrain junction, and posterior to the otic vesicle).

Structure	Level	Pattern	Image	Note
TS18: head mesenchyme	Present	Graded	1C	Expressing cells were present in the head mesenchyme, particularly in the region between the eye, forebrain, and nose.
TS18: branchial arch	Present	Regionally restricted	1C	Expression was detected in the posterior regions of the branchial arch.
TS18: 2nd branchial arch	Present	Regionally restricted	1C	Expression was detected in the posterior regions of the hyoid arch.
TS18: trunk mesenchyme	Present	Regionally restricted	1C	Expressing cells were observed from the first somites to the level of the hindlimb buds in the same locations as cells expressing Dct (TRP-2) mRNA.

Structure	Level	Pattern	Image	Note
TS18: head mesenchyme	Present	Regionally restricted	1E	Expressing cells were localized in a stripe originating at the mid-to-hindbrain junction and extending towards the eye.
TS18: trunk mesenchyme	Present	Regionally restricted	1E	Positive cells were detected in the lateral mesenchyme.
TS18: neural tube	Present	Regionally restricted	1E	Positive cells were detected in the dorsal neural tube.
TS18: forelimb bud	Present		1E
TS18: hindgut	Present		1E
TS18: hindlimb bud	Present		1E

Structure	Level	Pattern	Image	Note
TS19: trunk somite	Present	Spotted	2C	Expression was dispersed over the somite surface.
TS19: trunk mesenchyme	Present	Spotted	2C	Expression was detected in the lateral mesenchyme.
