Structure	Level	Pattern	Image	Note
TS20: oral epithelium	Strong	Regionally restricted	1C	Expression was down-regulated in the diastema but was maintained at high levels in incisor and molar placodes.
TS20: dental placode	Strong	Widespread	1C	Expression marked the entire dental epithelium.

Structure	Level	Pattern	Image	Note
TS26: molar enamel organ	Strong	Regionally restricted	1G	Expressed in the inner enamel epithelium, the precursors of enamel producing ameloblasts, but it was also detected, at somewhat lower levels, in the outer enamel epithelium and in stellate reticulum in both first and second molars.
