TS13: allantois	Present		2A
TS13: paraxial mesenchyme	Present		2A
TS13: future prosencephalon	Absent		2A
TS13: embryo	Weak	Regionally restricted	2A	Expression was weak in the posterior embryonic domain.

Structure	Level	Pattern	Image	Note
TS14: ear	Strong	Regionally restricted	2F	Strongest expression was detected in the endoderm and ectoderm epithelia of the future tympanic membrane region.
TS14: allantois	Present		2F
TS14: intraembryonic coelom	Present		2F
TS14: somite	Present		2F
TS14: paraxial mesenchyme	Present	Regionally restricted	2F	Expression was detected in the paraxial tissue at the cervical region.

Structure	Level	Pattern	Image	Note
TS18: embryo mesenchyme	Present	Non-Uniform	2K	Expression was detected in the cephalic and cervical regions. Expression in the cephalic flexure mesenchyme and surrounding the primary head and anterior cardinal vein and dorsal aorta was more intense.
TS18: head mesenchyme	Present	Non-Uniform	2K

Structure	Level	Pattern	Image	Note
TS20: dermis	Present		4A
TS20: skin	Present	Regionally restricted	4D , 4A	Expression was abundant in the five pairs of mammary gland placodes.
TS20: head mesenchyme	Present	Regionally restricted	4A	Abundant expression was more evident around the primary head vein and the cephalic ganglia.
TS20: myotome	Present	Regionally restricted	4D , 4A	Expression was detected in the most anterior myotomes at the inter limb area and more restricted to their dorsal lip in the rest of the embryo.
TS20: tail somite	Present	Regionally restricted	4A	Expression was detected in tail somites but absent in its distal extremity.
TS20: forelimb mesenchyme	Present	Regionally restricted	4A	Expression was detected in the mesenchyme surrounding the marginal vein. Expression in the dorsal muscle anlagen was evident.
TS20: hand	Present	Regionally restricted	4A	Expression was stronger in the distal region of the prospective digits. The dorsal central domain of expression in the autopod was wider.

Structure	Level	Pattern	Image	Note
