摘  要:
双翅目昆虫细胞系广泛应用于遗传学、发育生物学、分子生物学、人和动物体病原学以及昆虫抗微生物肽的研究。本研究建立了一株新的棕尾别麻蝇Sarcophaga peregrina胚胎细胞系。该细胞系的原代培养始于2008年11月17日,取材于棕尾别麻蝇晚期胚胎组织,在Shields&Sang M3昆虫培养基中于28℃恒温培养,在第26天进行第1次传代,至今已历时21个月,传代72次,生长状态稳定,被命名为Sp-E-HNU11。该细胞系的细胞形态主要呈梭形和近圆形,杂以少量巨型细胞,紧密贴壁生长。细胞群体倍增时间为42 h。染色体数目一般为10条或12条,为二倍体或亚二倍体细胞系;除一对颗粒状微型染色体外,其他染色体呈短杆状。细胞系的β-萘酯酶和谷草转氨酶同工酶谱上分别显示出1条和3条酶带。随机引物扩增多态性(random amplified polymorphic DNA,RAPD)分析结果显示,该细胞系与小菜蛾细胞系Px-E-HNU12、草地贪夜蛾细胞系IPLB-Sf-9和家蚕细胞系Bm-21E-HNU5呈现明显不同的带型特征。Sp-E-HNU11细胞系的建立为昆虫抗微生物肽及其他相关的研究工作增添了新的研究工具和生产载体。

摘  要:
Dipteran cell lines are widely used for studies of genetics,molecular biology,developmental biology,the host-parasite relationship in insect-borne pathogenic microbes and insect antimicrobial peptides.A new cell line from Sarcophaga peregrina,designated as Sp-E-HNU11,has been established.The primary culture from minced embryos of S.peregrina was initiated on November 17,2008,grown in Shields & Sang M3 insect cell medium at 28℃,and was split into two 26 days later.Since then,it has been subcultured for 72 passages.The cells,mainly round or spindle-shaped,adhere tightly to the flask.The population doubling time was 42 h.Most cells in metaphase observed were sub-diploid and contained ten or twelve chromosomes,which were short pole-like except two micro chromosomes.β-naphthyl esterase and aspartate aminotransferase isozymes of this cell lines displayed one and three bands,respectively,in sodium dodecyl sulfate polyacrylamide gel electrophoresis.In random amplified polymorphic DNA analysis,the Sp-E-HNU11 cells had a banding pattern markedly different from the ones of Px-E-HNU12,IPLB-Sf-9 and Bm-21E-HNU5 cells.The establishment of the new cell line would provide an additional tool and vector for research in insect antimicrobial peptides and related fields.
