Peritoneal macrophages from mice infected with Bacille Calmette-Guérin (BCG) and from normal mice were examined for their effects in vitro on thymidine uptake by 10 murine lymphomas, a murine fibroblast line, and a guinea pig hepatoma. Only the murine fibroblast line showed growth inhibition in the presence of BCG macrophages. For the majority of tumors, normal macrophages were profoundly stimulatory to tumor cell DNA synthesis, while BCG macrophages were much less stimulatory, without being frankly inhibitory. The effect of 2-mercaptoethanol on tumor cell growth was also studied. All lymphomas stimulated to grow more rapidly in vitro by normal macrophages were stimulated to a similar degree by 2-mercaptoethanol.
研究了感染卡介苗(BCG)的小鼠和正常小鼠的腹腔巨噬细胞在体外对10种鼠淋巴瘤、1种鼠成纤维细胞系和1种豚鼠肝癌细胞摄取胸苷的影响。只有鼠成纤维细胞系在存在卡介苗巨噬细胞的情况下表现出生长抑制。对于大多数肿瘤,正常巨噬细胞对肿瘤细胞DNA合成有显著的刺激作用,而卡介苗巨噬细胞的刺激作用则小得多,且无明显抑制作用。还研究了2-巯基乙醇对肿瘤细胞生长的影响。所有在体外被正常巨噬细胞刺激而生长更快的淋巴瘤,也被2-巯基乙醇刺激到类似程度。
