Figure 1. Staufen2 expression in the endoderm and isolated gut tissue. a: Transverse section through embryo at NF10 showing punctate expression of staufen2 throughout the mesendodermal precursor cells (arrowheads) as well as in the dorsal marginal zone (DMZ). b: Transverse section through embryo at NF15 showing Staufen2 expression within the archenteron roof (Ac) endoderm (arrowheads). Expression is also detected in the mesoderm (Mes). c: NF35 embryos showing Staufen2 expression throughout the head, in the spinal cord and in the dorsal (dp) and ventral (vp) pancreatic buds. d: Sagittal section through Staufen2 expressing region of NF35 embryo showing broad expression in the endoderm (en) and in the spinal cord (sc). e,f: Whole guts from NF40 and NF44 tadpole, expression was found throughout the pancreas, liver and stomach, becoming slightly stronger at later stages. St, stomach; L, liver; dp, dorsal pancreas; vp, ventral pancreas. Reproduced with permission of the Publisher, John Wiley & Sons. |
