The ultrastructure of the tight junctional complex of pubertal ram lamb Sertoli cells was studied in immersion-fixed samples and related to clinical data and a light microscopical classification of the degree of spermatogenesis attained in the corresponding seminiferous tubule. Although the process followed the general mammalian developmental trend for tight junction complex formation, 2 unusual ultrastructural features were detected: the presence of an active Golgi complex during the early stage of tight junction formation and the transitory presence of ribosomes on both faces of the ectoplasmic cisternae bordering the developing junctions. The significance of these findings is discussed.
在浸固定样本中研究了青春期公绵羊羔支持细胞紧密连接复合体的超微结构，并将其与临床数据以及相应生精小管中精子发生程度的光镜分类相关联。尽管该过程遵循了哺乳动物紧密连接复合体形成的一般发育趋势，但检测到两个不寻常的超微结构特征：紧密连接形成早期存在活跃的高尔基体复合体，以及在发育中连接相邻的外质池两面短暂存在核糖体。讨论了这些发现的意义。
