The ultrastructure of human corpora lutea obtained during the 6th, 10th, 16th, and 35th week of pregnancy is reported. Differences between the established luteal cell of pregnancy and the transitory luteal cell of the menstrual cycle are noted. In pregnancy the luteal cell is more compartmentalized into a peripheral mass of ER (endoplasmic reticulum) and a central area where mitochondria and Golgi complexes are concentrated. The latter area extends to a cell surface where microvilli face on a perivascular space. Long bundles of filaments are prominent within the luteal cell cytoplasm and, in contiguous cells, appear to arise from adjacent desmosomal regions. Bilateral subsurface cisternae of granular ER at lateral cell borders appear to be areas of specialized junctional surfaces. Certain luteal cells with irregular nuclear membranes are also characterized by vesicular aggregates enclosed within a single membrane. These aggregates are found within the peripheral nucleoplasm or the perinuclear cytoplasm. Their single limiting membrane often appears continuous with either the inner or outer leaflet of the nuclear membrane.
本文报道了在妊娠第6周、第10周、第16周和第35周获取的人黄体的超微结构。文中指出了妊娠黄体细胞与月经周期短暂黄体细胞之间的差异。在妊娠期间，黄体细胞更明显地分隔为内质网（ER）的外周团块以及线粒体和高尔基体复合体集中的中央区域。后一区域延伸至细胞表面，此处微绒毛朝向血管周围间隙。长束状细丝在黄体细胞胞质内很突出，并且在相邻细胞中，似乎起源于相邻的桥粒区域。细胞外侧边界处颗粒内质网的双侧表面下池似乎是特化连接表面的区域。某些核膜不规则的黄体细胞还具有被单层膜包裹的囊泡聚集体的特征。这些聚集体见于外周核质或核周胞质内。它们的单一限制膜常常看起来与核膜的内小叶或外小叶连续。
