摘要: 胎牛成纤维细胞是细胞重编程和去甲基化研究的常用材料。本文以胎牛成纤维细胞为材料,用不同浓度的DNA去甲基抑制剂药物5-氮杂-2’-脱氧胞苷分别处理24、48 和72 h 后,研究其对胎牛成纤维细胞的增殖、活力、细胞周期分布和凋亡率的影响。结果显示,5-氮杂-2’-脱氧胞苷以浓度依赖性的方式抑制胎牛成纤维细胞的增殖、活力,并增加细胞的总凋亡率。其中,用浓度低于0.1 μmol/L 的5-氮杂-2’-脱氧胞苷处理24 h 时,胎牛成纤维细胞受到的不利影响最小。这也说明采用相对低浓度的DNA去甲基抑制剂处理体细胞对于细胞的重编程是有益的。

Abstract: Fetal bovine fibroblast cells (FBFCs) are widely used in cellular reprogramming and methylation. In this study, the effects of 5- azacytidine-2’- deoxycytidines (5-Aza-CdR), a DNA methylation inhibitor on the physiological characteristics of FBFCs were investigated. The FBFCs derived from a bovine fetus were treated with 5-Aza-CdR at different concentrations for 24, 48 and 72 h, respectively, to determine the changes of cell proliferation, viability, cell cycle distribution and apoptosis rates. The results demonstrated that 5- Aza- CdR treatment in the FBFCs resulted in a decrease of cell proliferation, cell viability, and an increase of total cell apoptosis in a dose-dependent manner. The best treatment strategy for 5-Aza-CdR was less than 0.1 μmol/L for 24 h, which showed minimal adverse effects on FBFCs. The above results indicate that the low dose DNA demethylation inhibitor treatment in FBFCs is beneficial for cell reprogramming.
