CIL:24574

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.本数据集收录了猴肾细胞培养物中曼氏巴兰第阿米巴（Balamuthia mandrillaris）组序列显微影像的单帧画面。随附照片为伪足（pseudopodia）尖端的放大视图，用于展示其柔韧性与运动特性；另一组照片则展示了该阿米巴穿刺猴肾细胞质膜（plasma membrane）的过程：该组照片的第一幅依次呈现了细胞膜出现凹陷、伪足尖端回缩，以及阿米巴尖端压迫区域的细胞膜随后发生破裂的动态变化。细胞膜最终破裂可能由蛋白水解酶（proteolytic enzyme）的释放所介导。相关样本制备的详细信息可查阅细胞图像库（Cell Image Library，CIL）编号为CIL:19325的条目。
