TS11: yolk sac mesoderm	Present		4b/c , 4a
TS11: trophoblast giant cell	Present		4a

Structure	Level	Pattern	Image	Note
TS15: yolk sac mesenchyme	Present	Regionally restricted	5a/b , 5c/d	Expression was detected in the mesodermal layer of the yolk sac. In blood islands, the expression was restricted to the peripheral cell layer. In contrast, hematopoietic cells in the center of the blood islands were not labeled.
TS15: spongiotrophoblast	Present	Regionally restricted	5a/b	Expression in the placenta was highest in the outer spongiotrophoblast layer.
TS15: vascular plexus	Present	Regionally restricted	5e/f , 5a/b	Expression was detected in the perineural vascular plexus.
TS15: dorsal aorta	Present		5a/b , 5e/f

Structure	Level	Pattern	Image	Note
TS19: atrium endocardial lining	Present		6a
TS19: heart ventricle	Present		6a

Structure	Level	Pattern	Image	Note
TS19: blood vessel endothelium	Present	Regionally restricted	6b	Expression was detected in the endothelial lining of the dorsal aorta.
TS19: dorsal aorta	Present	Regionally restricted	6b	Expression was detected in the endothelial lining of the dorsal aorta.

Structure	Level	Pattern	Image	Note
TS19: intersomitic blood vessel	Present		6c

Structure	Level	Pattern	Image	Note
TS19: vascular plexus	Present	Regionally restricted	6d	Expression was detected in the meningeal vascular plexus.
TS19: brain vascular element	Present	Single cells	6d	Single cells in the neuroectoderm were labeled suggesting that vascular sprouts show expression.
