Figure Caption

Fig. 1 Inhibition of Notch signalling increases differentiation of beta-cells. In situ hybridizations showing insulin (A–D) somatostatin (PPSS2) (E–H) and glucagon (I–L) expression in mib mutants and DAPT-treated embryos. The pancreatic area is depicted. Insulin and somatostatin expression, in blue, is increased in mib mutants and DAPT-treated embryos (C, D, G, H) compared with controls (A, B, E, F). Conversely, glucagon expression is reduced or absent (compare K, L with I, J). Embryos in panels A, E, I and B, F, J should be compared with embryos in panels C, G, K and D, H, L, respectively. Embryos have been hybridized at 72 hpf and are presented in a ventral view with anterior to the left. Scale bar in panel A is 50 μm.
