Probe:	IMAGE clone 1180771
Probe preparation:	Antisense RNA

Structure	Level	Pattern	Image	Note
TS21: primary palate epithelium	Strong	Regionally restricted	1A	Expressed in the nasal side.
TS21: primary palate mesenchyme	Strong	Regionally restricted	1A	Expressed in the nasal side.

Structure	Level	Pattern	Image	Note
TS22: primary palate mesenchyme	Present	Non-Uniform	1C	The expression was broad in the nasal side and narrow in the oral side, but was hardly seen in the mesenchyme on either side of the medial edge epithelium seam.
TS22: primary palate epithelium	Present	Regionally restricted	1C	Expressed in the nasal/oral side epithelium.

Structure	Level	Pattern	Image	Note
TS23: primary palate mesenchyme	Present	Regionally restricted	1E	Expressed just around the bone-forming areas of the palate.

Structure	Level	Pattern	Image	Note
TS21: primary palate mesenchyme	Present	Regionally restricted	3A	Expressed in the nasal side.

Structure	Level	Pattern	Image	Note
TS22: primary palate mesenchyme	Present	Regionally restricted	3C	Little expression in the central part.
TS22: primary palate epithelium	Present	Regionally restricted	3C	Expressed in the nasal/oral side epithelium. Expression was undetected in the medial edge epithelium.

Structure	Level	Pattern	Image	Note
TS23: primary palate epithelium	Present	Regionally restricted	3E	Expression was undetected in the medial edge epithelium.
TS23: primary palate mesenchyme	Present	Regionally restricted	3E	Expressed just around the bone-forming areas of the palate. Expression was never detected in the central part.
