Structure	Level	Pattern	Image	Note
TS17: retina	Present	Regionally restricted	7A	Expression was detected in ventral and dorsal retina.
TS17: olfactory placode	Present		7A
TS17: otocyst	Present	Regionally restricted	7A	Expression was detected in the dorsal margin of the otic vesicle. Expression was transient and was not detected after E10.5.
TS17: olfactory epithelium	Strong		7A

Structure	Level	Pattern	Image	Note
TS15: optic vesicle	Present	Regionally restricted	7B	Expression was detected in the dorsal and ventral margins of the optic vesicle.
TS15: head surface ectoderm	Present	Regionally restricted	7B	Expression was detected in a large area of overlying surface head ectoderm.

Structure	Level	Pattern	Image	Note
TS17: head surface ectoderm	Weak		7C
TS17: neural retina	Present	Regionally restricted	7C	Expression was more pronounced in the ventral neural retina.
TS17: olfactory epithelium	Strong		7C

Structure	Level	Pattern	Image	Note
TS19: head surface ectoderm	Present	Regionally restricted	7D	Expression was detected where the ectoderm invaginates at the dorsal and ventral margins of the optic cup.
TS19: neural retina	Present	Regionally restricted	7D	Expression was more pronounced in the ventral neural retina. Staining was also transiently seen in the dorsal neural retina through E11.5.
TS19: olfactory epithelium	Present	Regionally restricted	7D	Starting at E11.5, expression became progressively more restricted to the dorso-lateral neuroepithelium.

Structure	Level	Pattern	Image	Note
TS20: neural retina	Present	Regionally restricted	7F	Expression in neural retina is distinct in the ventral domain by E12.5.

Structure	Level	Pattern	Image	Note
TS23: neural retina	Weak		7G

Structure	Level	Pattern	Image	Note
TS23: olfactory epithelium	Present	Punctate	7H
TS23: nasal mesenchyme	Present	Regionally restricted	7H	A punctate expression was noted in the mesenchymal stroma directly underlying the sensory epithelium. Expression was restricted to discreet zones within the developing turbinates.
