Fig 6 — Lateral views of embryos with a nuclear lacZ reporter (brown) driven by FasII-GAL4 (#46123). (A) Stage 11 embryo in which the anterior (amg) and posterior (pmg) midgut are stained. (B) Stage 13 embryo displaying continuous staining throughout the gut tissue, including the foregut (fg), midgut (mg) and hindgut (hg). (C, C’) Early stage 15 embryos in which the esophagus (es) is starting to loop. By this stage the visceral mesoderm that forms the visceral muscles surrounding the gut has migrated to the epithelial lining, but we see no evidence that the FasII line expresses in this tissue. (D) Late stage 15 embryo with persistent staining throughout the gut. (E) Early stage 16 embryo in which the proventriculus (pv) has started to form. Expression is widespread and continues to stage 17/early larval stages but at weaker levels.
