The presence and distribution of vimentin, a subunit of intermediate filaments, in the neural lobe and in the pars intermedia of the cat, rabbit and rat pituitary glands were investigated immunocytochemically. In the pars intermedia, our study revealed the presence of vimentin in glial-like cells located between glandular secretory cells of the three species and in the cells of the marginal layer of the cat and rat hypophyseal cleft. In the neural lobe of the cat and rabbit pituitary glands, there was a large amount of cell processes and immunoreactive pituicytes. In contrast, in the rat neural lobe, few pituicytes exhibited immunoreactivity, and these were located principally in the posterior region near the pituitary stalk. The significance of immunoreactive vimentin in these cells is discussed.
采用免疫细胞化学方法，研究了中间丝亚基波形蛋白在猫、兔和大鼠垂体神经叶及中间部的存在情况和分布。在中间部，我们的研究显示，波形蛋白存在于这三个物种腺分泌细胞之间的类胶质细胞中，以及猫和大鼠垂体裂边缘层的细胞中。在猫和兔垂体的神经叶中，有大量的细胞突起和免疫反应性垂体细胞。相比之下，在大鼠神经叶中，很少有垂体细胞表现出免疫反应性，且这些细胞主要位于靠近垂体柄的后部区域。文中讨论了这些细胞中免疫反应性波形蛋白的意义。
