Structure	Level	Pattern	Image	Note
TS14: myotome	Present		1A/B	Expression specifically in myotomal cells which have formed under the dermatome.
TS14: neural tube	Absent		1A/B	Expression in the neural tube is at or below the level of detection at this stage.

Structure	Level	Pattern	Image	Note
TS15: somite	Present	Scattered	2C	Scattered expression over the entire somite.
TS15: neural tube	Present	Diffuse	2C	Diffuse expression in neural tube at a level roughly comparable to that in the somites.
TS15: hindgut	Absent		2C	Authors report there was no expression in other embryonic structures such as the embryonic hindgut.

Structure	Level	Pattern	Image	Note
TS17: myotome	Present	Regionally restricted	3A/B	Expression in a mature myotome near the forelimb bud and more recently formed caudal myotomes.
