Most gonadotropes in the pituitary of male Suncus murinus L. are immunostained with both LH beta and FSH antisera, whereas only a few gonadotropes are positive only for LH beta. The former gonadotropes consist of polygonal or polyhedral cells of medium size, and can be identified by the presence of two types of secretory granules of low density: smaller ones (about 150-250 nm in diameter) which are spherical in shape, and larger ones of irregular form with a maximum diameter of about 1,500 nm. The endoplasmic reticulum is not prominent, while the Golgi apparatus is distinct. Mitochondria are found throughout the cytoplasm but are often concentrated in and around the region of the Golgi apparatus. These fine structural features are somewhat similar to those of the classical Barnes "FSH cells" and Kurosumi-Oota "FSH cells".
雄性麝鼩脑垂体中的大多数促性腺激素细胞同时被促黄体生成素β（LHβ）和促卵泡生成素（FSH）抗血清免疫染色，而只有少数促性腺激素细胞仅对LHβ呈阳性。前者促性腺激素细胞由中等大小的多边形或多面体细胞组成，可通过存在两种低密度分泌颗粒来识别：较小的颗粒（直径约150 - 250纳米）呈球形，较大的颗粒形状不规则，最大直径约1500纳米。内质网不突出，而高尔基体明显。线粒体遍布细胞质，但常集中在高尔基体区域及其周围。这些精细结构特征与经典的巴恩斯“FSH细胞”和黑住 - 太田“FSH细胞”的特征有些相似。
