| IG. 3. Expression pattern analysis of endodermal markers in stage 15 explants by whole-mount in situ hybridization. (A–E) Xlhbox8 expression. Notice that expression of Xlhbox8 is only seen in WEM and AEM explants, but not in PEM or WE explants. In isolated whole guts at stage 42, Xlhbox8 is expressed in the pancreas and the stomach. (F–J) IFABP expression. IFABP is expressed in WEM, AEM, and PEM explants, but not in WE explants. Also, IFABP is expressed in both AEM and PEM explants, as predicted by the fate map. In isolated whole guts, IFABP is expressed from the base of the stomach through the middle of the intestine. No IFABP expression is detected in the posterior intestine. (K–O) Xcad2 expression. Xcad2 is also expressed in WEM, AEM, and PEM explants. In contrast to IFABP, however, Xcad2 is expressed more highly in PEM explants than in AEM explants. In isolated whole guts, Xcad2 is expressed from the beginning of the small intestine through to the proctodeum. (P–T) Edd expression. Edd is expressed in all four explants. It is not expressed throughout the AEM explants, but is expressed throughout the PEM explants. In contrast to the other markers, Edd is expressed throughout the WE explants. In isolated whole guts at this stage, expression has become downregulated in the pancreas or stomach. |
