Structure	Level	Pattern	Image	Note
TS21: molar mesenchyme	Strong		1a/b
TS21: jaw mesenchyme	Strong	Regionally restricted	1a/b	Expressed in the mesenchyme beneath the oral epithelium around the tooth germs.

Structure	Level	Pattern	Image	Note
TS22: lower jaw molar dental papilla	Present		1c/d
TS22: dental sac	Present	Regionally restricted	1c/d	Slightly expressed in the dental sac of the cap stage tooth germs.
TS22: jaw mesenchyme	Weak	Regionally restricted	1c/d	Expression in the mesenchyme beneath the oral epithelium around the tooth germs was weak.

Structure	Level	Pattern	Image	Note
TS24: lower jaw molar dental papilla	Present		1e/f	Expression was downregulated.
TS24: jaw mesenchyme	Trace	Regionally restricted	1e/f	Expression was hardly recognized in the mesenchyme beneath the oral epithelium around the tooth germs.

Structure	Level	Pattern	Image	Note
TS26: lower jaw molar dental papilla	Present	Regionally restricted	1g/h	No expression in the late bell stage tooth germs of mandibular first molars, but it was clearly detected in the mandibular second molar (early bell stage, 1j).
TS26: lower jaw 1st molar	Absent		1g/h

Structure	Level	Pattern	Image	Note
TS26: lower jaw molar dental papilla	Present	Regionally restricted	1i/j	Clearly detected in the mandibular second molar.
TS26: lower jaw 2nd molar	Present	Regionally restricted	1i/j	Expressed in the dental papilla.

Structure	Level	Pattern	Image	Note
TS27: lower jaw 1st molar	Absent			There was no expression in the tooth germs of the mandibular first molars.
