From: Ascl1b and Neurod1, instead of Neurog3, control pancreatic endocrine cell fate in zebrafish
Pancreatic expression of ascl1b and neurod1 is repressed by Notch signaling. Fluorescent WISH showing pancreatic expression of ascl1b (A-B) and neurod1 (C-D) in wild-type (wt) embryos (A, C) and mind bomb (mib) mutants (B, D). Confocal projection images. All views are ventral views of 15 hpf embryos with anterior part to the left. Scale bars : 50 µm hpf, hours post fertilization; WISH, whole-mount in situ hybridization.
