细胞毒T淋巴细胞系细胞株(CTLL)是一组用正常的或预先经过F_(4-5)肿瘤细胞免疫刺激过的小鼠脾细胞,经过二次用同样的F_(4-5)肿瘤细胞作混合细胞培养后获得的细胞株。它们的生存增殖必须特异地依赖白细胞
The cytotoxic T lymphocyte cell line (CTLL) is a group of mouse splenocytes that have been immunostimulated with normal or previously F 4- (4-5) tumor cells and treated twice with the same F 4-5 tumor Cells were obtained after mixed cell culture. Their survival and proliferation must be specifically dependent on white blood cells
