Structure	Level	Pattern	Image	Note
TS22: molar epithelium	Present	Regionally restricted	4G/I , 4A , 4D/F , 4C	Mostly expressed in the lingual dental epithelium and epithelial tip. Most of the BrdU+ cells were Sox2+.
TS22: oral epithelium	Present	Regionally restricted	4J/L , 4C , 4A	Expressed in the lingual oral epithelium that was coupled to the Sox2+ lingual dental epithelium. Most of the BrdU+ cells were Sox2+.

TS22: molar epithelium	Present	Regionally restricted	7B	Expressed in the lingual epithelium of the dental stalk.
TS22: oral epithelium	Present	Regionally restricted	7B	Expressed in the oro-lingual epithelium.

TS21: oral epithelium	Present		7G
TS21: molar epithelium	Present	Regionally restricted	7G	Expressed at the very distal region making a U-shape surrounding the dental epithelial tip.

Structure	Level	Pattern	Image	Note
TS21: oral epithelium	Present		7I
TS21: molar epithelium	Present	Regionally restricted	7I	Expressed at the very distal region making a U-shape surrounding the dental epithelial tip. The posterior tip showed widespread expression, while the more anterior regions showed a restriction to the lingual side. At the tip the widespread expression was located in an area of flat epithelium, which thickened anteriorly.

TS21: oral epithelium	Present		7J
TS21: molar epithelium	Present	Regionally restricted	7J	Expressed at the very distal region making a U-shape surrounding the dental epithelial tip. The posterior tip showed widespread expression, while the more anterior regions showed a restriction to the lingual side. At the tip the widespread expression was located in an area of flat epithelium, which thickened anteriorly.
