用透射电子显微镜、扫描电子显微镜,冷冻蚀刻等方法,研究了人及哺乳动物甲状腺上皮的超微结构。人材料四例,大鼠、小鼠,家兔材料各10只,观察结果如下:上皮多为立方形、细胞间有圆孔并有细胞连接。扫描电镜结果,外表面有圆形小孔、内表面有微绒毛,中心鞭毛。冷冻蚀刻观察,可见核表面有大量核孔,细胞质中粗面内质网、线粒体、高尔基复合体、溶酶体。细胞间可见紧密连接,缝隙连接。 The ultrastructure of human and mammalian thyroid epithelium was studied by transmission electron microscopy, scanning electron microscopy, freeze-thawing and so on. Four cases of human material, rat, mouse, rabbit material 10, the observations are as follows: Epithelial mostly cubic, round holes between cells and cell connections. SEM results, the outer surface of a circular hole, the inner surface of microvilli, the center flagellum. Frozen etching observations, showing a large number of nuclear surface nuclear, rough endoplasmic reticulum in the cytoplasm, mitochondria, Golgi complex, lysosomes. The cells can be seen close connection, gap connection.
