多年来,人们一直试图建立血吸虫病主要致病原的持续分裂细胞系,即体外培养血吸虫细胞,但未获得满意的结果。血吸虫细胞在体外难以传代及分类培养,到目前为止尚未找到一种有效的裂变剂。1 997年,李靓如等[1 ] 以细胞工程学技术完成了猪囊尾蚴细胞系的建立及其生物学性质的研究, For many years, people have been trying to establish a persistent dividing cell line that is the major causative agent of schistosomiasis, that is, culturing schistosome cells in vitro, but satisfactory results have not been obtained. Schistosome cells in vitro is difficult to passage and classification of culture, so far has not found an effective fission agent. In 1997, Li Liangru et al [1] completed the establishment of cysticercus cellulosae cell line and its biological properties by using the technology of cell engineering,
