在这里, 我们提出了一个延时形态测量方案, 以跟踪在预防干预和升温后恢复过程中囊胚收缩和再膨胀的强度。该方案可在配备延时显微镜的体外受精实验室中应用, 并建议在开发最佳囊胚玻璃化方法时使用。

该形态化协议允许在之前的玻璃化干预和预热后恢复期间监测囊肿收缩和再膨胀的强度,并提供对病毒玻璃化方法有效性的见解。该技术的主要优点是,它可以应用于配备延时显微镜的体外受精实验室和配备高级图像编辑软件的计算机。在扩张的第五天或第六天,对至少几个内细胞质量细胞和有凝聚力的肌萎缩球体进行冲击,形成0.4至0.7毫秒的激光脉冲,孔径从4.3到9.4微米不等,切线对着佐纳佩图西达和两个相邻的三角细胞的交界处。

然后,让爆震完全或部分坍塌五分钟。接下来,使用一个微小的移液器,无菌地将平衡介质添加到九孔培养皿微滴区域的孔中,专为延时显微镜和记录而设计。添加所有介质后,用大约 30 微升的平衡介质覆盖微滴区域。
