目的:使用无血清培养基培养可稳定表达马来丝虫半胱氨酸蛋白酶抑制剂基因(Brugia malayi cystatin, Bm-CPI)的人宫颈癌细胞(Hela)。方法:将已获得的Bm-CPI稳定转染的Hela细胞株,进行无血清培养并观察Hela细胞的维持时间和培养过程中Hela细胞的形态变化。结果:无血清培养基培养Hela细胞可维持细胞的正常生长。结论:无血清培养基可以逐步代替含血清的培养基,为后续Hela细胞扩大培养和Bm-CPI基因重组蛋白纯化提供依据。
目的:使用無血清培養基培養可穩定錶達馬來絲蟲半胱氨痠蛋白酶抑製劑基因(Brugia malayi cystatin, Bm-CPI)的人宮頸癌細胞(Hela)。方法:將已穫得的Bm-CPI穩定轉染的Hela細胞株,進行無血清培養併觀察Hela細胞的維持時間和培養過程中Hela細胞的形態變化。結果:無血清培養基培養Hela細胞可維持細胞的正常生長。結論:無血清培養基可以逐步代替含血清的培養基,為後續Hela細胞擴大培養和Bm-CPI基因重組蛋白純化提供依據。

Objective:To culture stably expressing Brugia malayi cystatin(Bm-CPI) gene of Hela cells in serum-free medi-um. Methods:The monoclonal cell strains of recombinant plasmid pcDNA3.1(+)-Bm-CPI were cultured in suspension culture with serum-free media, then were observed the maintain time and morphological changes of the Hela cells in culture super-natant. Results:Hela cells cultured in serum-free medium grew well. Conclusion:The medium containing serum can be com-pletely substituted by serum-free medium, which sets up a base for further study of Hela cells being expanded and Bm-CPI recombinant proteins purification.
