Among the cells of the pituitary generally believed to produce glycoprotein gonadotropin (GTH) five forms were distinguished, based on the amount and the diameter of granules and globules and the appearance of the rough endoplasmic reticulum. In sham-operated trout so-called "globular" cells predominated, whereas after ovariectomy these were replaced by so-called "cisternal" cells, suggesting that both belong to one GTH-cell type. In addition, ovariectomy caused a strong increase in plasma GTH-levels. This indicates that the transition from globular to cisternal cells is accompanied by extrusion of GTH, and thus points to a storage of GTH in the granules and globules. It is argued that one of the five forms has the morphological characteristics of thyrotropic cells and may not produce glycoprotein GTH.
一般认为能产生糖蛋白促性腺激素（GTH）的垂体细胞，根据颗粒和球状体的数量、直径以及粗面内质网的外观，可区分出五种类型。在假手术的鳟鱼中，所谓的“球状”细胞占主导，而卵巢切除术后，这些细胞被所谓的“池状”细胞取代，这表明两者属于同一GTH细胞类型。此外，卵巢切除术导致血浆GTH水平大幅升高。这表明从球状细胞向池状细胞的转变伴随着GTH的分泌，因此表明GTH储存在颗粒和球状体中。有人认为这五种类型中的一种具有促甲状腺细胞的形态特征，可能不产生糖蛋白GTH。
