Fig. 1. Endoderm-enriched transcripts identified by microarray analysis. (A) The spatial expression profile of 276 endoderm-enriched sequences (264 genes), based on microarray analysis, in different regions of the stage 11 gastrula. The average intensity, normalized to stage 11 whole embryo is shown on a log scale. The diagrams below the graph indicate the different regions of the embryo. An, animal cap ectoderm; Veg, endoderm-enriched vegetal tissue; Eq, mesendoderm-enriched equatorial tissue; We, whole embryo stage 11. (B) The pie diagram indicates the predicted functions on the endoderm-enriched genes based on NCBI Unigene annotation, GO ontogeny and blast searches.
