提出了一种优化的方案,该方案能够使用近红外飞秒激光在中期I期间消耗小鼠卵母细胞中的细胞质微管组织中心。

该方案提供了一种极好的策略来选择性消融细胞质 MTOCs,细胞质 MTOCs 是小鼠卵母细胞中纺锤体定位的关键调节因子。因此有助于我们了解调节卵母细胞减数分裂的分子机制。该技术允许在活卵母细胞内进行靶向消融,空间精度高,对细胞的光毒性影响最小。该方案可用于诱导不同讲师的选择性机械扰动,而不会改变细胞活力。该方案需要在尽可能短的时间内消融所有细胞质 MTOC 的技术技能,以避免损害卵母细胞的活力。因此,在进行实际实验之前多次练习这种技术是必不可少的。首先,用谷氨酰胺和米力农补充 CZB 培养基,并将其放入培养箱中。准备采集和培养菜肴。分别在 60 和 35 mm 培养皿中制备四微滴收集培养基和两微滴培养基。并用矿物油覆盖它们。将收集皿放在载玻片加热器上,并在 37 下孵育
