  Figure 6. Xenopus tropicalis FoxA1. Whole-mount in situ hybridization analysis of tFoxA1 mRNA expression in tropicalis embryos. A: A vegetal view of a midgastrula embryo shows tFoxA1 transcripts in the endoderm. B: A midsagittal section of the same embryo (dorsal to the left) shows strong tFoxA1 expression in the chordomesoderm and weaker expression throughout the endoderm. The dark staining in the animal cap is pigment. C: A dorsal view (anterior up) of a stage 18 embryo shows tFoxA1 expression in the notochord and also in ciliated cells of the epithilium. A lateral view of a tail bud embryo (D) and a cross-section of the same embryo (E) shows tFoxA1 transcripts expressed throughout the endoderm, as well as in the notochord and floor plate. F: Analysis of stage 40 embryos shows that tFoxA1 transcripts mark the endoderm late in development. st., embryonic stage.
