双光子激光的细胞膜损伤是一种广泛应用的评价膜加盖能力的方法, 可应用于多种细胞类型。在这里, 我们描述了一个协议的体外活成像膜加盖在 dysferlinopathy 患者细胞后双光子激光消融。

该程序的总体目标是量化肌营养不良患者细胞中的质膜可修复性。这种方法可以帮助回答肌营养不良症的关键问题,例如给定突变与膜再密封动力学之间的关系是什么。该技术的主要优点是它允许实时定量活细胞中的膜重密封动力学。

首先在 37 摄氏度的二氧化碳培养箱中,在含有 40 毫升生长培养基的 T225 培养瓶中培养成纤维细胞。当培养物达到 70% 至 80% 汇合度时,用每次洗涤 40 毫升 PBS 冲洗细胞两次,然后在 37 摄氏度下加入 5 毫升 0.05% 胰蛋白酶 5 分钟。当细胞分离后,用 40 毫升新鲜生长培养基终止反应,并以每毫升 100, 000 个细胞的浓度将 2 毫升细胞接种到 35 毫米胶原蛋白涂层玻璃底板中,在 37 摄氏度和 5% 二氧化碳下孵育过夜。
