Clusters of chief cells from a fragment of human parathyroid adenoma possess relatively few rough endoplasmic reticulum (RER) cisternae with scattered annulate lamella (AL) pores in cytoplasmic sectors close to the nucleus. Some of these cisternae exhibit winding profiles with smooth segments lying very close to the outer nuclear membrane. Other groups of cells exhibit well-developed stacks of RER either in continuity with or separated from AL. Two other tumor fragments show chief cells with few RER cisternae scattered in the cytoplasm and possess stacks with various amounts of AL and/or paired cisternae (PC), occasionally at perinuclear sites. Compartmental continuity between AL and PC is a frequent finding. Pore density in AL varies considerably between the stacks from different cells.
来自人甲状旁腺腺瘤片段的主细胞簇在靠近细胞核的细胞质区域中，具有相对较少的粗面内质网（RER）池，并有散在的环状片层（AL）孔。其中一些池呈现蜿蜒的轮廓，其平滑段非常靠近外核膜。其他细胞群则显示出发育良好的RER堆叠，与AL连续或与AL分离。另外两个肿瘤片段显示主细胞的细胞质中散在着少量RER池，并具有含有不同数量AL和/或成对池（PC）的堆叠，偶尔位于核周部位。AL和PC之间的隔室连续性是常见的发现。来自不同细胞的堆叠之间，AL中的孔密度差异很大。
