NTZ exposure induced developmental abnormalities in zebrafish embryos. Live zebrafish embryos were exposed to vehicle control (0.1% DMSO) or NTZ at various concentrations (0, 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0 and 8.0 mg/L) at 6 hpf. Statistics of (A) mortality, (B) hatching rate and (C) embryo malformation rate are shown. (D–G) Representative images of embryo morphology at 72 hpf. (H) The body length of the embryo at 72 hpf. (I) The yolk area of the embryo at 72 hpf. Note:
