文题释义:
多房棘球绦虫体外培养模型:指通过使用各种方法在体外模拟多房棘球绦虫生长环境,使其在体外完成整个生长发育全过程,主要由最初有宿主成分干扰的“组织碎片培养模型、胶原蛋白膜培养模型及大规模液体培养模型”发展到“无宿主成分干扰培养模型”以及最新的“原代细胞培养模型”几种方式构成。
泡状棘球蚴病:是由多房棘球绦虫寄生于人体引发的一种人兽共患病,该病起病隐匿,潜伏期长,发展迅速,呈侵润性增殖,被发现时一般都处在疾病晚期。
摘要
背景:
多房棘球绦虫原头节的体外成囊培养是提取与研究其生发层干细胞的实验基础。D-MEM与RPMI-1640是最适宜用于泡球蚴体外培养的商业培养基,HeLa细胞与大鼠肝癌细胞(ATCC No. CRL-1600)也是常用饲养细胞。
目的:构建多房棘球绦虫体外培养模型,观察泡球蚴在不同饲养细胞[HeLa细胞与大鼠肝癌细胞(ATCC No.CRL-1600)]及含有体积分数10%胎牛血清的不同培养基[D-MEM(高/低糖型)与RPMI-1640]下生长情况。
方法:预先培养HeLa细胞及大鼠肝癌细胞(ATCC No.CRL-1600),从新疆石河子大学第一附属院实验动物中心提供的感染多房棘球绦虫6个月以上的种鼠体内提取原头节后分别与不同饲养细胞及培养基体外共同培养。实验经石河子大学医学院第一附属医院医学伦理委员会批准,批准号:2015-018-01,批准时间:2017-04-07。实验根据饲养细胞与培养基组合分为6组,每组加入1×106饲养细胞与50 mL含体积分数10%胎牛血清的培养基及5 000个原头节,Ⅰ组:HeLa细胞与1640培养基培养;Ⅱ组:HeLa细胞与D-MEM(高糖型)培养基培养;Ⅲ组:大鼠肝癌细胞与1640培养基培养;Ⅳ组:大鼠肝癌细胞与D-MEM(高糖型)培养基培养;Ⅴ组:HeLa细胞与D-MEM(低糖型)培养基培养;Ⅵ组:大鼠肝癌细胞与D-MEM(低糖型)培养基培养,观察泡球蚴原头节的生存、生长和发育,每隔7 d计算原头蚴成囊率,使用目镜测微尺测量囊泡平均直径大小。
结果与结论:①原头蚴在6种组合中均可长期存活,大部分都形成囊泡,囊泡直径分布在1-6 mm;②培养第56天原头蚴成囊率和囊泡平均直径均为大鼠肝癌细胞与D-MEM(高糖型)培养基组效果最佳(P < 0.05),成囊率(72.08±1.79)%,囊泡平均直径(3.379±0.199) mm;③囊泡囊液蛋白定量检测结果显示6组囊液蛋白含量均低于体内囊泡,Ⅳ组蛋白含量高于其他5组(P < 0.05);④结果证实:同条件下D-MEM(高糖型)培养基囊泡大小与数量优于其他2种培养基。大鼠肝癌细胞(ATCC No.CRL-1600)作为饲养细胞囊泡大小与数量优于HeLa细胞。D-MEM(高糖型)与大鼠肝癌细胞(ATCC No.CRL-1600)共同作用的环境下原头蚴生长发育的成囊率及囊泡大小最佳,可作为体外培养泡球蚴原头蚴获得囊泡的最优选择。

Abstract:

BACKGROUND: The cystic culture of Echinococcus multilocularis protoscolex in vitro is the experimental basis for extracting and studying its original cells. D-MEM and RPMI-1640 are the most suitable commercial media for in vitro culture of Echinococcus multilocularis, and HeLa cells and rat hepatoma cells (ATCC No. CRL-1600) are also commonly used feeder cells.
OBJECTIVE: A culture model of Echinococcus multilocularis in vitro was established to observe the growth of Echinococcus multilocularis in different feeder cells (HeLa cells and rat hepatoma cells (ATCC No.CRL-1600) and different media (D-MEM (High and Low glucose type) and RPMI-1640) containing 10% fetal bovine serum.
METHODS: HeLa cells and rat hepatoma cells (ATCC No. CRL-1600) were pre-cultured. The Echinococcus multilocularis metacestode was extracted from mice infected with Echinococcus multilocularis for more than 6 months (provided by the Laboratory Animal Center of the First Affiliated Hospital of Shihezi University, Xinjiang Uygur Autonomous Region) and co-cultured with different feeder cells and culture media. The experiment has been approved by the First Affiliated Hospital of School of Medicine, Shihezi University, approval number: 2015-018-01 on April 7, 2017. The experiment was divided into six groups according to the combination of feeder cells and medium. Each group was added 1x106 feeder cells, 50 mL medium containing 10% fetal bovine serum and 5 000 protoscolexes. Group I: HeLa cells and 1640 medium; group II: HeLa cells and D-MEM (high glucose type) medium; group III: hepatocellular carcinoma cells and 1640 medium; group IV: hepatocellular carcinoma cells and D-MEM (high glucose type) medium; group V: HeLa cells and D-MEM (low glucose type) medium; group VI: hepatocellular carcinoma cells and D-MEM (low glucose type) medium. The survival, growth and development of the protoscolex were observed. The rate of protoscolex vesicle formation was calculated every 7 days, and the average diameter of vesicle was measured using microscope micrometer.
RESULTS AND CONCLUSION: (1) Protoscolex could survive for a long time in all four combinations. The vesicle diameter ranged from 1 to 6 mm. (2) On day 56, the cyst formation rate and average vesicle diameter of protocephalus were the best in rat hepatocellular carcinoma cells and D-MEM (high sugar type) culture medium group (P < 0.05), the cyst formation rate was (72.08±1.79)% and the vesicle diameter was (3.379±0.199) mm. (3) Quantitative analysis of vesicle fluid protein showed that the contents of vesicle fluid protein in six groups were lower than those of vesicles in vivo, and the group IV was higher than those in the other five groups (P < 0.05). (4) These results indicate that under the same conditions, the vesicle size and quantity of D-MEM medium are better than those of the other two media. Rat hepatocellular carcinoma cells (ATCC No. CRL-1600) are better than HeLa cells in size and number of vesicles as feeder cells. The cyst formation rate and vesicle size of D-MEM and rat hepatocellular carcinoma cells (ATCC No. CRL-1600) are the best, which can be used as the optimal choice for obtaining Echinococcus multilocularis vesicles in vitro.
