Fig. 10 Expression Patterns and Morpholino Knockdown in Zebra Fish Embryos.
A) Developmental expression of zebra fish Lisch-like and Lsr-like orthologs. Lisch-like RNA was hybridized in situ to whole-mount zebra fish embryos at 48 hours post-fertilization (hpf), dorsal view with anterior towards the top; and 72 hpf, lateral view with anterior towards the top, ventral towards the right and yolk removed. Lsr-like RNA was hybridized at 48 hpf and 34 hpf. Ll panels show ventral views of embryos with yolks removed and anterior towards the top. Lsr-like panels show the same image captured in the focal plane of the anterior (ap) and posterior (pp) pancreatic buds, respectively. i, intestine; ph, pharynx; pn, pronephric ducts; l, liver; ap, anterior pancreatic bud; pp, posterior pancreatic bud; p, pancreas (after anterior and posterior bud fusion); b, brain; o, otic vesicle. B) Morpholino knockdown of Lisch-like and Lsr-like orthologs at 48 hpf. Two dimensional ventral views (anterior towards top) of confocal stacks of 48 hpf embryos, uninjected or injected with 15 ng morpholino: control, Lsr-like sp1, and Lisch-like ATG. Gut-GFP transgene expression (green); insulin immunolabelling (red).
