正常腺垂体:嗜酸性细胞、嗜碱性细胞和嫌色细胞(高倍镜)


正常腺垂体显微镜图像。腺垂体包含嗜酸性细胞、嗜碱性细胞和嫌色细胞。染色方法多样,如要准确识别特定激素分泌物,免疫组织化学染色法是必要的。

激素分泌分类如下:
粉红色嗜酸性细胞分泌生长素( GH )和催乳素( PRL );
暗紫色的嗜碱性细胞分泌促肾上腺皮质激素( ACTH ),促甲状腺激素(TSH)和卵泡刺激素(FSH)和黄体生成素(LH)。
淡染的嫌色细胞几乎没有胞质颗粒,但也有分泌活动。

The normal microscopic appearance of the adenohypophysis is shown here. The adenohypophysis contains three major cell types: acidophils, basophils, and chromophobes. The staining is variable, and to properly identify specific hormone secretion, immunohistochemical staining is necessary. A simplistic classification is as follows:
The pink acidophils secrete growth hormone (GH) and prolactin (PRL)
The dark purple basophils secrete corticotrophin (ACTH), thyroid stimulating hormone (TSH), and gonadotrophins follicle stimulating hormone-luteinizing hormone (FSH and LH)
The pale staining chromophobes have few cytoplasmic granules, but may have secretory activity.
