Expression pattern of Pitx and asymmetrical pharyngeal organs markers. a1–c3, e1-e3 Pitx is expressed in the left anterior-dorsal half of the embryos from the N1 neurula stage to N3 neurula stage (a1-a3, e1-e3), Lhx3, Prop1 is activated in the prospective preoral pit region from the N1 stage to N3 stage (b1-b3, c1-c3), as shown by WISH and transvers sections in (a1”’–c3”). f1–h3 The expression of right-sided organ makers, FoxE4 (f1-f3), Nkx2.1 (g1-g3), and Hex (h1-h3) from N1 to N3 stage, as shown by WISH and transverse sections (f1”–h3”’). The lines in a1–h3 indicate the position of transverse sections of the embryos. The embryos detected by WISH are all in dorsal views. A, anterior; P, posterior; D, dorsal; V, ventral; L, left side; R; right side. Scale bars: 50 μm
