该方案描述了一种改进的程序,用于在缺乏颗粒细胞的斑马鱼中快速分离干净的 I 期卵母细胞,从而为卵母细胞特异性研究提供了一种便捷的方法。

本研究的重点是建立快速有效地分离斑马鱼中纯第一阶段卵子的工艺,同时消除颗粒细胞污染。主要目的是开发一种方法,在卵母细胞特定研究领域进行更精确的分析,特别是在基因组和表观遗传学研究中。斑马鱼的卵母细胞被单层颗粒细胞包裹。

由于颗粒细胞的数量和体积存在显著差异,因此很难快速分离颗粒细胞和卵母细胞,因此很难获得用于特异性分析的纯卵母细胞样本,尤其是在基因组相关研究中。与机械方法和以前的检测方法相比,这种方法具有生存优势。首先,改进的检测缓冲液更温和,有助于分离颗粒细胞,同时最大限度地减少对卵母细胞的损伤。
