Human endometrium taken during the early to mid-secretory portion of the menstrual cycle is studied with the electron microscope. A description of the nucleolus is given. In addition, an unusual structure within the endometrial cell nucleolus is described, consisting of amorphous matrix, 150-A dense granules, and a series of tubular channels. This structure is named the nucleolar channel system. A description is given of the geometric variability of the nucleolar channel system, its contents, and its relationship to the cytoplasm. The morphologic basis for a nucleolar-cytoplasmic interrelationship via the nucleolar channel system is described. Some of the implications of this relationship are discussed. The work of previous investigators on the nucleolar channel system is discussed.
对月经周期分泌期早期至中期获取的人体子宫内膜进行了电子显微镜研究。给出了核仁的描述。此外，还描述了子宫内膜细胞核仁内一种不寻常的结构，它由无定形基质、150埃致密颗粒和一系列管状通道组成。这种结构被命名为核仁通道系统。对核仁通道系统的几何变异性、其内容物及其与细胞质的关系进行了描述。阐述了通过核仁通道系统实现核仁与细胞质相互关系的形态学基础。讨论了这种关系的一些意义。还讨论了先前研究人员关于核仁通道系统的工作。
