Effects of morpholino-mediated knock down of Notch ligands on the differentiation of pancreatic cell populations. Panels A–D: insulin and glucagon expression at 24 hpf in control and deltaA-morphant embryos. glucagon-expressing cells are decreased in number in deltaA morphants (D). Panels E–H: glucagon expression in the pancreas (E, F) and gut (G, H) is increased in jagged1b-morphant embryos (F, H) compared with controls (E, G). Panels I–J: trypsin expression is decreased in jagged1b morphant embryos. Panels K–N: expression of endocrine and exocrine markers in jagged2-morphant embryos. insulin (red) expression is increased and trypsin (blue) expression decreased in jagged2-morphants (panels L and L′ blow up) compared with controls (panels K and K′ blow up). glucagon expression profile in jagged2-morphants is enlarged (N) reflecting the increased size of the beta-cell cluster. Embryos are in ventral view with anterior to the left. Stages are indicated at the bottom right of each frame. The scale bar is 50 μm. |
