Whole-body bone-staining images of a WT fish (45dpf, body length= 17.77 mm) and of an imbs deletion mutant zebrafish (47dpf, body length= 19.28mm). a) Whole body bone staining of a WT zebrafish, b) an area anterior to the dorsal fin of the WT zebrafish, and c) an area posterior to the dorsal fin of the WT zebrafish (Arrowheads point at imbs). d) whole body bone staining of a mutant zebrafish with partial loss of imbs, e) an area anterior to the dorsal fin of the mutant zebrafish, and f) an area posterior to the dorsal fin of the same mutant zebrafish. In image e, imbs are completely missing in the area anterior to the dorsal fin of the mutant fish. In image f, imbs are still present but appear shorter compared to ones in the WT zebrafish as shown in b and c, respectively. Arrowhead indicated imbs.
