脑垂体由腺垂体和神经垂体构成。根据HE和Mallory三色法等标准方法的染色特性,传统上将腺垂体的细胞分成三类:(1)嫌色性细胞,约占细胞总数的50％,含有少量细胞浆,光镜下不显颗粒,然而电镜证明它也有少许分泌颗粒;(2)嗜伊红或嗜酸性细胞,约占细胞总数的40％,在人类聚集成簇,特别是在腺垂体的两侧;(3)嗜硷性细胞,用苏木素或苯胺蓝染色时,胞浆中有蓝染的颗粒。嗜酸性细胞又称α-细胞,嗜硷性细胞又称β-细胞,而嫌色细胞可能是它们的前身。
Pituitary by the pituitary and neurohypophysis. According to the staining properties of standard methods such as HE and Mallory trichromatography, cells of the pituitary gland have traditionally been divided into three categories: (1) chromophobe cells, accounting for about 50% of the total number of cells, containing a small amount of cytoplasm, under light microscopy (2) eosinophilic or eosinophilic cells, accounting for about 40% of the total number of cells, clustered in humans clustered, especially on both sides of the pituitary gland; (3) addicted to Alkaline cells, stained with hematoxylin or aniline blue, the cytoplasm of blue dye particles. Eosinophils, also known as α-cells, basophils also known as β-cells, and chromophobe may be their predecessor.
