Probe:	Stra6 cDNA2
Probe preparation:	Antisense labelled with digoxigenin RNA

Structure	Level	Pattern	Image	Note
TS17: trunk mesenchyme	Present	Regionally restricted	2A	Expression was detected in the flank mesenchyme. The domain appeared to be continuous with the limb bud dorsal expression domains and was restricted to a relatively narrow stripe.
TS17: forelimb bud	Present	Regionally restricted	2A	Expression was detected along the dorsal and ventral sides of the forelimb buds.
TS17: hindlimb bud	Present	Regionally restricted	2A	Expression was detected along the dorsal side of the hindlimb buds.
TS17: dorsal root ganglion	Present		2A

Structure	Level	Pattern	Image	Note
TS17: trunk mesenchyme	Present	Regionally restricted	2B	Expression was detected in the flank mesenchyme. The domain appeared to be continuous with the limb bud dorsal expression domains and was restricted to a relatively narrow stripe.
TS17: forelimb bud	Present	Regionally restricted	2B	Expression was detected along the dorsal and ventral sides of the forelimb buds. Both the dorsal and ventral domains extended toward the proximal aspect of the limbs, but did not reach their distal extremities.
TS17: hindlimb bud mesenchyme	Present	Regionally restricted	2B	Expression remained restricted to the posterior and proximal mesenchyme of the hindlimb.
TS17: dorsal root ganglion	Present		2B

Structure	Level	Pattern	Image	Note
TS18: hindlimb bud	Present	Regionally restricted	2C	A subtle ventral expression domain was detected in the hindlimb bud.
TS18: forelimb bud	Present	Regionally restricted	2C	Two proximal expression domains were detected along the dorsal side of the forelimb bud.
TS18: dorsal root ganglion	Present		2C
TS18: face mesenchyme	Present		2C
TS18: trunk mesenchyme	Present	Regionally restricted	2C	Expression was detected in the flank mesenchyme. The domain appeared to be continuous with the limb bud dorsal expression domains and was restricted to a relatively narrow stripe.

Structure	Level	Pattern	Image	Note
TS17: trunk mesenchyme	Present	Regionally restricted	2D	Expression was detected in the flank mesenchyme.
TS17: forelimb bud	Present	Regionally restricted	2D	An additional domain of expression was detected along the ventral margin of the forelimb.

Structure	Level	Pattern	Image	Note
TS17: forelimb bud	Present	Regionally restricted	2E	Expression was detected along the dorsal and ventral sides of the forelimb buds. Both the dorsal and ventral domains extended toward the proximal aspect of the limbs, but did not reach their distal extremities.

Structure	Level	Pattern	Image	Note
TS17: trunk mesenchyme	Present	Regionally restricted	2F	Expression was detected in the flank. mesenchyme. The domain appeared to be continuous with the limb bud dorsal expression domains and was restricted to a relatively narrow stripe.
