来源:Bise, T. 等人。胸腔内注射,用于成年斑马鱼心脏的研究。 J. Vis. Exp.(2019 年)。
该视频描述了使用胸腔内注射将化合物输送到成年斑马鱼心脏的技术。
1. 准备胸腔内注射的鱼
2. 心包显微注射

图 1:成年斑马鱼的胸腔内 (IT) 注射。(A) 带细丝(6 英寸,直径 1.0 毫米)的拉动显微注射毛细管的照片和所用拔针程序的值。(B) 拉动的显微注射毛细管的照片,其中细丝(6 英寸,直径 1.0 mm),填充了 2.5 μL 含有 10% 酚红的溶液。拉出的针尖最大长度为 7 毫米。(C) IT 注入程序的示意图。(D) IT 注射程序的照片。该图是从 Bise 等人修改而来的。图 C 和 D 中的数字对应于该程序的相同步骤:(1) 将鱼腹面朝上放在加湿的海绵上。穿刺部位(三角形中的红点)位于胸部中央靠近鳃的地方。(2) 针头刺入心包。红点表示穿刺部位。(3) 通过观察红色溶液在心包腔内的扩散来监测注射。(E) IT 注入方案。注射毛细血管与体轴之间的角度应在 30° 和 45° 之间,以避免心脏穿刺。(F) IT 注射指定体积后 1 小时鱼胸部的照片。白色箭头指向红色组织,这可能表示内出血
