Nom1 is indispensable for pancreas proliferation but not for specification.
(A–F) Dorsal views, anterior to the top. (A, B) Expression of prox1 (D, E) and pdx-1 (C, F) in the nom1 morphants is comparable to that in WT embryos at 36 hpf but reduced gata6 expression in liver (arrow) and pancreas (arrowhead) of nom1 morphants is obvious. (G) Anti-phospho Histone H3 (pH 3) staining for control and nom1 morphant embryos at 3 dpf. Red: GFP staining. Green: pH 3 staining. The signal of pH 3 staining in the pancreas of morphants is recognizably decreased. (H) Quantification of pH 3-positive cell numbers. Data were collected from 10 embryos. Error bars mean±SD. **P<0.01.
