CIL:24565

A frame from the grouped movie of a Balamuthia mandrillaris ameba within a culture of monkey kidney cells. Accompanying photographs are enlargements of the tips of pseudopodia to demonstrate their flexibility and movement, and a second set of photographs demonstrate the puncture of the plasma membrane of a monkey kidney cell. The first shows an indentation in the cell membrane, the withdrawal of the pseudopodia tip and the subsequent rupture of the membrane in the area indented by the amebic tip. The eventual break in the membrane may have resulted from the release of a proteolytic enzyme. Details of the preparation can be found in CIL:19325.

本素材为猴肾细胞培养物中曼氏巴鲁斯阿米巴（Balamuthia mandrillaris）组映影像的单帧画面。配套照片为伪足（pseudopodia）尖端的放大图，用于展示其柔韧性与运动状态；第二组照片则展示了猴肾细胞质膜被穿刺的全过程。第一组照片依次呈现了细胞膜凹陷、伪足尖端回缩，以及随后在被阿米巴尖端压陷的区域发生的膜破裂过程。最终的膜破裂现象可能由蛋白水解酶（proteolytic enzyme）的释放所引发。相关制备细节可查阅CIL:19325。
