Fig. 6. Comparative gene expression patterns of the T-box genes in X. laevis embryos. (A-Q) Spatial expression of zVegT (A-E), Eomes (F- J), Xbra (K-N), and Tbx6 (O-Q) was detected by WISH from stage 9 to stage 11. Arrowheads indicate the initial zygotic expression of individual genes. The VegT antisense probe recognized both mVegT and zVegT. The top and bottom panels show the vegetal view with dorsal side up and dorsolateral view, respectively. (R) RT-PCR reveals temporal expression of T-box genes. |
