Figure 2. Regulation of org-1 expression in the trunk visceral mesoderm.

Figure 2

(A,B) Stage 10 and stage 11–12 wildtype embryos stained for Org-1 protein. (C,D) Stage 10 and stage 11–12 tin346 embryos stained for Org-1 showing strongly reduced expression in the trunk visceral mesoderm and missing founder cell restriction. (E) Stage 10 bapDf mutant embryos display only slight reduction of Org-1 expression domains during early development. (F) bapDf embryos of stage 12 display missing founder cell restriction of Org-1. (G,H) Loss of Bin function has no influence on Org-1 expression at early stages as well as during stage 12. (I) Ventral view of a stage 12 wildtype embryo stained for Org-1. (J) Ventral view of a stage 12 embryo with forced panmesodermal expression of a constitutively activated version of the Dpp-receptor Thickveins (tkvQ–D). The Org-1 expression domains have been extended into the ventral somatic mesoderm. Abbreviations: (vm) visceral mesoderm, (sm) somatic mesoderm.
