Fig. 1. Expression of regional epithelial markers in 3-day (stage 41) guts. In situ hybridization of 3-day Xenopus guts showing regional expression of markers along the anterior–posterior axis of the epithelium (dark blue). (A) Xsox2 anterior and posterior domains. (B) IFABP in the small intestine. (C) Xcad1 expression extends further posterior than IFABP, but not into the proctodeum. (D) Xcad2 expression is identical to that of Xcad1 in the gut. (E) Xhox3 marks the most posterior region of the gut, the proctodeum. (F) Regionalization of the 3-day gut based on the expression of these markers. Pa, pancreas; li, liver; st, stomach. |
