Fig. 2. (A) Cardiac expression of Isl1, Nkx2.5, GATA4, GATA5, GATA6b, Xmsr and Flk1 in Xenopus embryos at stages 15/16, 20, 24 and 29 as indicated. (B) Cardiac expression of Tbx20, Tbx1, Tbx5, BMP2, BMP4, Dkk1, and FGF8b at different developmental stages of Xenopus laevis as indicated. For embryos at stages 15/16 and 20 anterior views are presented, whereas embryos at stage 24 and 29 are shown from the ventral side, anterior is to the top. Dotted lines indicate the cement gland. |

Fig. 6. (A) Serial transverse sections indicate the expression of Isl1, Nkx2.5, GATA4, GATA5, GATA6b, Xmsr and Flk1 in Xenopus laevis embryos at stage 30/31. (B) Spatial expression of Tbx20, Tbx1, Tbx5, BMP2, BMP4, Dkk1 and FGF8b at stage 30/31. The upper row provides a lateral view. Dashed lines depict the level of sections A, B and C as indicated. Level A corresponds to the anterior region of the heart. Level B is at the level of the closing heart tube. Level C is at the posterior end of the heart where the IFT forms later in development. |
