Figure 6. Ptf1a overexpression promotes ectopic expression of candidate genes in the developing endoderm. All images are transverse section through the anterior endoderm. a,b: Stronger expression and expanded domain of hey1 in the anterior endoderm of a ptf1a mRNA injected embryo at NF32 (7/10). c,d: At NF36, expression of hey1 is stronger along the periphery of the endoderm (8/11). e,f: At NF32, syntaxin 1B expression is stronger in the dorsal endoderm and expands ectopically towards the ventral endoderm (7/10). g,h: Expression of syntaxin 1B is much stronger in the dorsal and ventral endoderm of ptf1a-injected embryos at NF36 (6/10). i,j: igfbp1 expression is expanded in the ventral endoderm but unchanged in the dorsal endoderm of ptf1a-injected embryos at NF32 (9/9). k,l: At NF36 ptf1a-injected embryos the punctate expression of igfbp1 is stronger and more abundant (8/11). m,n: Expression domain of hapln3 in the ventral endoderm is stronger and broader in ptf1a-injected embryos at NF32 (6/10). o,p: At NF36, expression of hapln3 is ectopically expressed in the ventral endoderm but unaffected in the dorsal endoderm (5/10). de, dorsal endoderm; ve, ventral endoderm.
