The expression pattern of kdm6bb during the early development stage of zebrafish. a, b Kdm6bb is detected at the early embryonic stage at 16-cell from the lateral and top view (a, b; n = 14 embryos) and blastula period (3.7 hpf) (c; n = 12 embryos) by whole-mount in situ hybridization. d–f Kdm6bb is expressed in the migrating primordium (d, e) and deposited neuromasts (f). The dotted lines of (d; n = 8 embryos) and (e; n = 10 embryos) outline the migrating primordia at higher magnification. White arrows in (f; n = 16 embryos) mark the neuromasts stained with kdm6bb along the trunk. The details of kdm6bb staining in magnified neuromasts are presented in (g). The experiment was duplicated for two times
