Fig. 1. Anatomy and gene expression in dissected Xenopus guts. A: Dorsal view of a gut from a 3-day-old embryo. B: Ventral view of a gut from a 3-day-old embryo. C: Gut from a 5-day-old embryo. D: Gut from a 7-day-old embryo. E: Stomach region from a 7-day-old gut. F: Boundary between small and large intestine of 7-day-old gut. G: Activity of endogenous alkaline phosphatase in 3-day gut. H: Activity of endogenous alkaline phosphatase in 7-day gut. Inset shows a section through stained gut (arrow highlights alkaline phosphatase staining (blue) in epithelium, arrowhead highlights mesodermal tissue counterstained green). I: Activity of endogenous alkaline phosphatase in stomach region of 7-day gut (1 and 2 show the first and second expression boundaries). J: Ventral view of IFABP expression in 3-day gut. K: Dorsal view of IFABP expression in 3-day gut. L: IFABP expression in 5-day gut. M: IFABP expression in 7-day gut. N: Endodermin expression in 3-day gut. O: Endodermin expression in 5-day gut. P: Endodermin expression in 5-day liver. Q: XlHbox8 expression in 3-day gut (highlighted by bracket). R: XlHbox8 expression in 7-day gut. In C-F the arrows mark the boundary between the stomach and the small intestine, and the arrowheads mark the boundary between the small intestine and the large intestine. st, stomach; si, small intestine; li, large intestine; pr, proctodeum; pa, pancreas; lv, liver; and gb, gall bladder.
