Probe:	Paraxis probe-1
Probe preparation:	Antisense labelled with S35 RNA
Visualized with:	Autoradiography

Structure	Level	Pattern	Image	Note
TS11: embryo mesoderm	Weak	Regionally restricted	2A/B	Expression is restricted to the primative mesoderm in the posterior region of the embryo.

Structure	Level	Pattern	Image	Note
TS13: head paraxial mesenchyme	Present	Regionally restricted	3A/B	Expression in the paraxial mesoderm and newly formed somites progressed caudally between 8.0 and 12.5 dpc.

Structure	Level	Pattern	Image	Note
TS15: trunk somite	Present	Regionally restricted	3C/D	Expression is found in the dermatome, myotome, and sclerotome of somites that have recently compartmentalized.

Structure	Level	Pattern	Image	Note
TS15: trunk paraxial mesenchyme	Present	Regionally restricted	3E/F

Structure	Level	Pattern	Image	Note
TS15: trunk somite	Present	Regionally restricted	3G/H	Expression is present in newly-formed caudal somites (at bottom) and is down-regulated in myotome of mature rostral somites(at top).

Structure	Level	Pattern	Image	Note
TS17: trunk somite	Present	Regionally restricted	3I	Strong expression is detected in the lateral sclerotomes; weak expression is seen in myotomes.
TS17: forelimb bud	Present	Regionally restricted	3I	Expression is localized to the dorsal region of the forelimb.

Structure	Level	Pattern	Image	Note
TS17: trunk paraxial mesenchyme	Present	Regionally restricted	5B	Transcripts are localized to somites.
TS17: limb	Present	Regionally restricted	5B	Expression is localized to cells in the proximal region of the limb bud.
