Fig. 1. Overlapping expression of Tbx6, XMyf5, XMyoD and Xwnt8 at the early gastrula stage analyzed by in situ hybridization. (A) Tbx6 is expressed in the lateral and ventral mesoderm of early gastrula. (B) XMyf5 shows similar expression pattern but is expressed at a lower level in the most ventral region. (C) XMyoD is expressed in a very similar pattern as Tbx6. (D) The expression of Xwnt8 is localized to the ventral region with a relatively lower level in the lateral mesoderm. The expression of all four genes is excluded in the dorsal region. |
