CIL:12604, Paramecium multimicronucleatum, cell by organism, eukaryotic cell, Eukaryotic Protist, Ciliated Protist. In Cell Image Library

High resolution image of a colchicine-treated cell, used in an attempt to disrupt its microtubules. We found that microtubules already formed are not disrupted in Paramecium multimicronucleatum. This open cytoproct shows the microfilaments around the retrieved membrane vesicles. The larger vesicles appear to be expanded ER as ribosomes can be seen on their cytosolic face. A long membrane tubule appears to be bound to a microtubular ribbon that may have its origin at the cytopharynx. TEM taken on 1/16/73 by R. Allen with Hitachi HU11A operating at 60kV. Neg. 8,100X.

本数据集为经秋水仙素（colchicine）处理后的细胞的高分辨率图像，该样本来自旨在破坏细胞微管结构的实验。研究团队发现，在多小核草履虫（Paramecium multimicronucleatum）中，已组装完成的微管并未被秋水仙素破坏。该图像中可见开放的胞肛（cytoproct），其周围环绕着回收膜囊泡的微丝结构。较大的囊泡疑似为扩张的内质网（endoplasmic reticulum, ER），因可在其胞质侧表面观察到核糖体附着。一条长膜小管似乎附着于一条微管带，该微管带的起源部位可能为胞咽（cytopharynx）。此透射电子显微镜（Transmission Electron Microscopy, TEM）图像由R. Allen于1973年1月16日拍摄，使用日立（Hitachi）HU11A型电镜，加速电压为60kV，放大倍数为8100倍。
