本文报道日本血吸虫童虫培养细胞的超微结构。透射电镜下，日本血吸虫童虫的培养细胞可分为圆颗粒形、鞭毛形、三角扇形、多角形和不规则形等，其中以圆颗粒形为主；它们一般呈高核质比例，核多呈圆形或椭圆形，异染色质常聚集成块状；胞质中含有丰富的游离核糖体、散在的线粒体，还有内质网、糖原颗粒等；不同组织来源的培养细胞按其各自的特征，可划分为生殖细胞、焰细胞、神经细胞、肥大细胞、肌肉细胞、体被下细胞 This article reports the ultrastructure of Schistosoma japonicum cultured cells. Under TEM, the cultured cells of Schistosoma japonicum were divided into round granular shape, flagellum shape, triangular fan shape, polygonal shape and irregular shape, among which round granular shape was the main part; Round or oval, heterochromatin often aggregated into lumps; the cytoplasm is rich in free ribosomes, scattered mitochondria, as well as the endoplasmic reticulum, glycogen particles; cultured cells of different tissues according to their respective The characteristics can be divided into germ cells, flame cells, nerve cells, mast cells, muscle cells, the body is under the cells
