In order to study the protection of β-carotene and vitamin C against the transformation of human lung fibroblasts cell induced by nickel sesquioxide, HLF cells were treated repeatedly by different concentrations of Ni2O3 in vitro.β-carotene (5.4mg/L) and vitamin C(1.8mg/L) were added into the media containing Ni2O3 (1.0mg/L) respectively. The identification of malignancy of the transformation of HLF cell was carried out by the tests of ConA and the growth on semisolid agar culture. The results showed that Ni2O3 could induce the malignant transformation of HLF cell. The transformed cell proliferated rapidly.

Cell lines was established in vitro cell culture system. Only one of it grows well during gene targeting operation. The sex of these cell lines was identified by Sry-PCR.Using lipotransfection method to transfer pZJ into pig fetal fibroblast cell. After 7 days G418 selection, 30 neo-positive cell clones were obtained, among them, 12 of which is non-green ones.

用Sry-PCR法和染色体核型分析法鉴定细胞系的性别，采用优化的脂质体转染法将pZJ转染猪胎儿成纤维细胞，经7天G418(600μg／ml)药物筛选，共获得30个neo阳性细胞克隆，其中12个为非绿色细胞克隆，仅有7个可以扩大培养。
