接触致畸可能导致出生缺陷。斑马鱼是确定的化学物质的致畸潜在有用的。我们通过暴露胚胎各级亚硝酸盐,并且也在曝光不同的时间证明斑马鱼的效用。我们表明,亚硝酸盐可能是有毒的,并导致严重的发育缺陷。

该程序的总体目标是用亚硝酸盐处理斑马鱼胚胎并确定其致畸作用。这种方法可以帮助回答发育毒理学领域的一些关键问题,例如评估化学物质对胚胎发育的致畸作用。该程序的主要优点是它使用在外部发育的斑马鱼胚胎,可以在显微镜下观察。

对于此处演示的实验,将野生型斑马鱼品系(例如 Tuebingen 品系)保持在 28.5 摄氏度和 14 小时和 10 小时的明暗周期。在收获鱼卵的前一天晚上,将鱼水和隔板加入配对水箱,并将雄鱼和雌鱼放在隔板的不同两侧。为确保产生足够的鸡蛋,设置 30 对鱼。
