The follicle cells, nurse cells and germinal epithelia, which are closely associated with the oocyte of Agriolimax reticulatus (Müller) during its development in the ovotestis, have been studied using light and electron microscopy. The various secretory, digestive and phagocytic activities of these cells have also been investigated using electron cytochemical tests for oxidisable polysaccharide, acid phosphatase and electron-opaque tracer molecules. The oocyte lies initially between the germinal epithelia and a layer of nurse cells but, as oocyte vitellogenesis proceeds, it becomes encapsulated by a layer of follicle cells. Both the follicle and the nurse cells are active in secretion and digestion and contain Golgi apparatus, granular endoplasmic reticulum and acid phosphatase-rich digestive vacuoles. The significance of these activities is discussed in relation to oocyte vitellogenesis, secondary envelope formation and the digestion and recycling of cellular material.
在光镜和电镜下，对与网纹蛞蝓（Müller）卵精巢中卵母细胞发育密切相关的卵泡细胞、滋养细胞和生殖上皮进行了研究。还使用针对可氧化多糖、酸性磷酸酶和电子不透明示踪分子的电子细胞化学测试，研究了这些细胞的各种分泌、消化和吞噬活动。卵母细胞最初位于生殖上皮和一层滋养细胞之间，但随着卵母细胞卵黄发生的进行，它被一层卵泡细胞包裹。卵泡细胞和滋养细胞都具有活跃的分泌和消化功能，含有高尔基体、颗粒内质网和富含酸性磷酸酶的消化液泡。结合卵母细胞卵黄发生、次级包膜形成以及细胞物质的消化和再循环，讨论了这些活动的意义。
