George E. Palade (2012) CIL:37207, Rattus, cardiac muscle cell. CIL. Dataset

Transmission electron micrograph of longitudinal section of rat heart cardiac muscle from the atrium. A darkly stained intercalated disc runs from upper left to lower right. Also prominent are groups of myofibrils running diagonally across the image and several mitochondria.
This 1960 TEM image has historical value as one of the earliest views of muscle ultrastructure.

该数据集包含一张电子显微镜下观察到的鼠心房心肌纵向切面的图像。图中可见一条从左上角至右下角呈暗染的闰盘，以及呈对角线分布的肌纤维群和多个线粒体。该1960年的透射电子显微镜（TEM）图像作为肌肉超微结构的早期观察之一，具有历史价值。图像由James D. Jamieson和耶鲁大学医学院细胞生物学系提供。
