This paper deals with the ultrastructural study of mature vampire bat Sertoli cells and their relationships with the different stages of testicular germ cells. In vampire bat seminiferous epithelium there are different types of junctional specializations among Sertoli cells and among Sertoli cells and different germ cells, with special emphasis to tight junctions and to junctions like as desmosomes. Ectoplasmic junctions through the Sertoli cells, including the smooth ER, are observed. These cellular interactions and their cytophysiological roles are discussed. Also are related some ultrastructural peculiarities of the Sertoli cell nucleus, nucleolus, cytoplasmic organelles and lipidic inclusions.
本文探讨了成年吸血蝙蝠支持细胞的超微结构研究及其与睾丸生殖细胞不同阶段的关系。在吸血蝙蝠的生精上皮中，支持细胞之间以及支持细胞与不同生殖细胞之间存在不同类型的连接特化，特别强调紧密连接和类似桥粒的连接。观察到通过支持细胞的胞质连接，包括滑面内质网。讨论了这些细胞间相互作用及其细胞生理作用。还阐述了支持细胞核、核仁、细胞质细胞器和脂质包涵体的一些超微结构特点。
