Structure	Level	Pattern	Image	Note
TS15: neural tube	Present	Regionally restricted	1A	Anterior expression boundary caudal to otic vesicle. Distance between the rostral most expressing neural tissue and the otic vesicle is indicated in the image.

Structure	Level	Pattern	Image	Note
TS17: neural tube	Present	Regionally restricted	1B	Authors report the rostral boundary of expression domain is more diffuse at E10.5 than at E11.5.

Structure	Level	Pattern	Image	Note
TS19: neural tube	Present	Regionally restricted	1C	Authors state the that the distance between otic vesicle and the most anterior expressing cells is reduced 2-fold between E9.5 and E11.5.

Structure	Level	Pattern	Image	Note
TS15: neural tube	Present	Regionally restricted	2A	Expression up to level of somite 4 in the neural tube.

Structure	Level	Pattern	Image	Note
TS15: neural tube	Present	Regionally restricted	2C	Expression up to level of somite 4 in the neural tube.

Structure	Level	Pattern	Image	Note
TS17: neural tube	Present	Regionally restricted	2F	Rostral boundary of expression located more rostrally than anterior expression limit of Raldh2 (Aldh1a2).

Structure	Level	Pattern	Image	Note
TS17: neural tube	Present	Regionally restricted	2H	Rostral boundary of expression located more rostrally than anterior expression limit of Raldh2 (Aldh1a2).
