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.
