Keyword:  hTERT基因人γδT细胞永生化电转染;
Abstract: 利用电击将外源基因hTERT与pTet-on调控质粒共转染人γδT细胞,建立可诱导的永生化人γδT细胞系.分离人PBMC,体外刺激增殖后经磁珠分选纯化,然后对其进行外源hTERT基因和pTet-on调控质粒的共同电转染,并加入强力霉素诱导目的基因表达.电转染程序T 23和T-20的效率分别为37.5%±0.9860%和30.5%±0.5590%.经鉴定,外源hTERT基因能够整合人γδT细胞基因组中并在诱导后表达.程序T-23的转染效率更高,强力霉素的有效诱导浓度是600ng/mL,志愿者本人的血清更利于电转后细胞的存活.
