Studies on the multiple compact tests of Schistosoma mansoni have revealed 2 principle cell types: germinal and non-germinal cells. Two morphological forms representing different stages in the cytomorphosis of the sustentacular cells have been considered. The polymorphic sustentacular cells which are conspicuously stained with potassium permanganate contain abundant ribosomal endoplasmic reticulum, glycogen particles and ribosomal masses in comparison with the germinal component of the testes. Golgi complexes with associated secretory bodies and vacuoles are present in the cells. The cytoplasm of the sustentacular cells interdigitate between other cells in the testes. Based on their morphology, nutritive, supportive and phagocytic functions have been attributed to the sustentacular cells. The possible recycling of nutrients by the cells is discussed. It is suggested that the cell regulate the production of spermatozoa from a nutritive viewpoint and also that the translocation of nutrients from the parenchyma to the testes is facilitated by these cells whose cytoplasm extends directly adjacent to the basal lamina.
生殖细胞和非生殖细胞。人们认为有两种形态形式代表了支持细胞细胞变形的不同阶段。与睾丸的生殖成分相比，用高锰酸钾显著染色的多形性支持细胞含有丰富的核糖体内质网、糖原颗粒和核糖体团块。细胞中存在带有相关分泌小体和液泡的高尔基体复合体。支持细胞的细胞质在睾丸中的其他细胞之间相互交错。基于其形态，营养、支持和吞噬功能已归因于支持细胞。讨论了细胞对营养物质可能的再循环。有人提出，从营养角度来看，这些细胞调节精子的产生，而且这些细胞质直接延伸至基底膜附近的细胞促进了营养物质从实质向睾丸的转运。
