Figure 2. Expression of novel pancreatic genes in dissected guts of tadpole stage embryos. Gene expression patterns were revealed by whole-mount in situ hybridization at three representative stages, stage 34-36, stage 40-41, and stage 42-43. These genes are expressed in the pancreatic rudiments of stage 34-36 embryos. The dorsal and ventral pancreatic buds are indicated with the black and white arrows, respectively and the liver bud is marked by an asterisk. A whole embryo was shown for HES3. While the Xenopus laevis gene designated here as HES3 (also known as Xenopus ESR2) has a best blastP match to human HES5, blastN to X. tropicalis and synteny relations identifies it as a gene distinct from tropicalis hes5 called hes3.
