From: Ascl1b and Neurod1, instead of Neurog3, control pancreatic endocrine cell fate in zebrafish
Impaired endocrine cell differentiation in neurod1 morphants. Ventral views with anterior to the left of WISH showing expression of insulin (A-C), somatostatin (D-F), ghrelin (G-I) and glucagon (J-L) in control (A, D, G, J), Mo1-neurod1 (B, E, H, K) and Mo2-neurod1 (C, F, I, L) morphants at 30 hpf. The quantifications on the right side of the figure represent the number of positive cells per embryo for controls and neurod1 morphants. Asterisks (***) indicate that the difference between cell number in controls and neurod1 morphants is statistically significant by Student’s t-test (P <0.001). Scale bars : 50 µm hpf, hours post fertilization; WISH, whole-mount in situ hybridization.
