Fusion of mouse peritoneal macrophages with SV40-transformed human cells, deficient in hypoxanthine guanine phosphoribosyltransferase, resulted in the formation of transformed somatic cell hybrids which contained, without exception, the human chromosome 7 carrying the SV40 genome. It is postulated that the hybridization of mouse nondividing cells with human cancer cells could permit the identification of the human "oncogenic" chromosome(s) present in human cancer cells, since such chromosome(s) should be retained by the totality of the mouse-human hybrid cells.
将缺乏次黄嘌呤鸟嘌呤磷酸核糖转移酶的SV40转化的人细胞与小鼠腹膜巨噬细胞融合,导致形成转化的体细胞杂种,无一例外,这些杂种都含有携带SV40基因组的人类7号染色体。据推测,小鼠非分裂细胞与人癌细胞的杂交可以鉴定出人癌细胞中存在的人类“致癌”染色体,因为这样的染色体应该会被所有的小鼠-人杂交细胞保留下来。
