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组分延时摄影影片（time lapse movies，CIL 11958-11962）中的一组，展示了减数分裂卵母细胞纺锤体（meiotic oocyte spindle）对玻璃显微针（glass microneedle）开展的各类显微操作（micromanipulation）的响应。该显微针从下方穿过卵皮质（egg cortex），抵达中期纺锤体（metaphase spindle）的内极。本影片经约10倍加速播放，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，其会自动回归初始位置与原有取向。借助偏振光学（polarizing optics）装置，可清晰观测到纺锤体及其空间取向。
