TS17: central nervous system	Present		3C	Expression in the neural tube.
TS17: tail unsegmented mesenchyme	Present		3C	Expression maintained in presomitc mesoderm.

Structure	Level	Pattern	Image	Note
TS17: tail	Present	Regionally restricted	3D	Expression pattern in presomitic mesoderm varied among embryos. Expression detected in middle presomitic mesoderm and tailbud.
TS17: tail unsegmented mesenchyme	Present	Regionally restricted	3D	Expression pattern in presomitic mesoderm varied among embryos. Expression detected in middle presomitic mesoderm and tailbud.

Structure	Level	Pattern	Image	Note
TS17: tail unsegmented mesenchyme	Present	Regionally restricted	3E	Expression in more anterior presomitic mesenchyme without the tailbud.
