Fig. 3 Embryonic expression of
X. laevis Nkx6 genes. A–C, J–L
Dorsal views, anterior to the
left; D–G, M–Q, T, W, X lateral
views, anterior to the left; H, I
blastopore views, dorsal to the
top; R lateral view, animal pole
to the top; S ventral view,
anterior to the top; U, V frontal
views, dorsal to the top. Black
broken oval lines show the
boundaries of blastopores. Black
broken lines indicate the positions
of corresponding sections.
Arrowheads indicate the expression
in the dorsal endoderm
(blue), the caudal hindbrain
(red), and the mandibular arch
(black). Paired arrows in b′ and
l′ show the boundaries of the
expression domains. b Blastocoel;
h heart; li liver; n notochord;
