Knockdown of z-idua caused defective head cartilage in zebrafish embryos. Using alcian blue staining to detect the head cartilage of zebrafish embryos at 120 hpf. Untreated embryos (control) and embryos injected with antisense morpholino oligonucleotides (MO) complementary with z-idua (z-idua-MO) were studied. (A,B) Lateral view; (C,D) Ventral view; (A,C) Untreated control embryos; and (B,D) z-idua-MO injected embryos. Loss of function of z-Idua caused deformed cranial cartilage and decreased number of cartilage cells. cb, ceratobranchial; ch, ceratohyal; ep, ethmoid plate; m, Meckel’s cartilage; pq, palatoquadrate; tr, trabecular plate. Scale bar: 100 μm.
