Liver expression of zebrafish jagged and notch genes. (A-C) Lateral view of wild-type 72-hpf larvae processed for RNA in situ hybridization using jagged 1 (A), jagged 2 (B) and jagged 3 (C) antisense probes. All three jagged genes are expressed in the larval liver (arrow), but jagged 2 expression is most pronounced. Expression in the branchial arches is also evident. (D-G) Lateral view of wild-type 72-hpf larvae processed for RNA in situ hybridization using notch 1a (D), notch 1b (E), notch 2 (F) and notch 5 (G) probes. All notch genes are expressed in the developing larval liver and the branchial arches.
