人成纤维细胞样细胞株产生的肿瘤细胞生长抑制因子(HFI)的发现、分离和体外生物学效应研究,最近已通过成果鉴定。完成这项研究的吴克复同志在澳大利亚进修期间,从人成纤维细胞样细胞株中发现了能抑制肿瘤细胞体外繁殖的HFI,经部分提纯测得HFI为分子量55,000的蛋 The discovery, isolation and in vitro biological effects of tumor cell growth inhibitory factor (HFI) produced by human fibroblast-like cell strains have recently been identified by results. Comrade Wu Kefu, who completed this study, discovered HFI, a fibroblast-like cell line, that inhibited the in vitro proliferation of tumor cells during the study in Australia. After partial purification, the HFI was measured as an egg with a molecular weight of 55,000.
