Fig. 4. Histological analysis of molecular markers expressed before and during fusion of the pancreatic rudiments. A) Stained sagittal section of a stage 39 tadpole showing both the dorsal and ventral pancreas. B) Close-up of the bracketed area in A. C) Islet1 RNA expression in a sagittal section of a stage 39 tadpole. D) Islet1 RNA expression in a transverse section of a stage 37 tadpole. E) Insulin protein expression in a transverse section of a stage 39 tadpole. F) NeuroD RNA expression in a transverse section of a stage 39/40 tadpole. G) Pax6 RNA expression in a transverse section of a stage 39/40 tadpole. The section in F is more anterior than in G.
