肝衰竭是全球死亡的主要原因之一,在美国,慢性肝病的死亡率正在急剧上升。健康的肝脏能够从毒性损伤中再生,但在晚期肝病中,肝脏再生的天然能力受损。斑马鱼已经成为研究再生的强大实验系统。它们是研究部分肝切除术后肝再生的理想模型,部分肝切除术是一种具有直接临床意义的手术,其中部分肝脏被手术切除,其余部分保持完整。部分肝切除术没有标准的方案;以前使用这种模型的研究使用了略有不同的方案,并报告了不同的结果。这里描述的是一个有效的,可重复的协议进行部分肝切除术在成年斑马鱼。我们使用这种技术来证明,斑马鱼是能够epimorphic再生的切除叶。该方案可用于进一步询问斑马鱼肝再生所需的机制。该方案描述了去除成年斑马鱼肝脏腹叶的程序,以研究肝脏再生。
Liver failure is one of the leading causes of death worldwide, and mortality from chronic liver disease is rising sharply in the United States. Healthy livers are capable of regenerating from toxic damage, but in advanced liver disease, the natural ability of the liver to regenerate is impaired. Zebrafish have emerged as a powerful experimental system for studying regeneration. They are an ideal model for studying liver regeneration from partial hepatectomy, a procedure with direct clinical relevance in which part of the liver is surgically removed, leaving the rest intact. There is no standard protocol for partial hepatectomy; previous studies using this model have used slightly different protocols and reported disparate results. Described here is an efficient, reproducible protocol for performing a partial hepatectomy in adult zebrafish. We use this technique to demonstrate that zebrafish are capable of epimorphic regeneration of the resected lobe. This protocol can be used to further interrogate the mechanisms required for liver regeneration in zebrafish. This protocol describes the procedure for removing the ventral lobe of the liver in adult zebrafish to enable the study of liver regeneration.
