CIL:11961

This is one of 4 grouped time lapse movies (CIL 11958-11962) revealing the responses of a meiotic oocyte spindle to various forms of micromanipulation by a glass microneedle. The needle is inserted, from below, through the egg cortex to the inner pole of the metaphase spindle. This movie, speeded up about 10-fold, illustrates the positional 'memory' of the system. After the spindle has been moved to the center of the cell, it returns to its original position and orientation. The spindle and its orientation are made visible by the use of polarizing optics.

本数据集为4组延时摄影影片（CIL 11958-11962）之一，展示了减数分裂卵母细胞纺锤体对玻璃显微针实施的各类显微操作的响应过程。显微针从下方插入，穿过卵皮层抵达中期纺锤体的内极。本影片经约10倍加速处理，直观呈现了该系统的位置「记忆」特性：当纺锤体被移至细胞中央后，其可恢复至初始位置与取向。借助偏振光学成像技术，纺锤体及其取向得以清晰显现。
