Abstract

Immunoelectron microscopic localization of prolactin (PRL) was studied in pituitary adenoma cells and in non-neoplastic PRL cells. The adenoma cells showed characteristic concentration of PRL in Golgi region which was ultrastructurally in Golgi saccules and in vesicular RER. In contrast, the non-neoplastic PRL cells showed lamellated RER which contained PRL. These results suggested disproportional production of PRL and its secretion in the adenoma cells.

摘要

在垂体腺瘤细胞和非肿瘤性催乳素（PRL）细胞中研究了催乳素的免疫电子显微镜定位。腺瘤细胞显示PRL在高尔基体区域有特征性聚集，在超微结构上位于高尔基体囊泡和泡状粗面内质网中。相比之下，非肿瘤性PRL细胞显示含有PRL的板层状粗面内质网。这些结果提示腺瘤细胞中PRL的产生及其分泌不均衡。
