The amount of embryonic antigens (EA) was estimated in 13 BALB/c fibrosarcomata by in vitro cell mediated cytotoxicity of anti-embryo spleen cells and by quantitative absorption of an anti-embryo antiserum. A direct relationship between amount of EA and tumour growing capacity was found. EA were detected also on fast dividing testicular cells. It is suggested that EA expression on tumour cells is related to a cell membrane function controlling mitosis rather than to a function specifically related to the neoplastic status. Tumour take of low doses of 2 EA-bearing sarcomata was found to be enhanced in anti-embryo immune BALB/c mice in comparison with that in normal and anti-fibroblast immune mice.
通过抗胚胎脾细胞的体外细胞介导细胞毒性以及抗胚胎抗血清的定量吸收,对13个BALB/c纤维肉瘤中的胚胎抗原(EA)量进行了估计。发现EA量与肿瘤生长能力之间存在直接关系。在快速分裂的睾丸细胞上也检测到了EA。有人提出,肿瘤细胞上EA的表达与控制有丝分裂的细胞膜功能有关,而不是与肿瘤状态特异性相关的功能有关。与正常和抗成纤维细胞免疫的小鼠相比,发现抗胚胎免疫的BALB/c小鼠中低剂量的2个携带EA的肉瘤的肿瘤接种率有所提高。
