Virus-like particles identical in morphology to the RNA tumor vi ruses have been observed by electron microscopy in six lines of murine L cells and one line of murine liver cells. Control cultures of embryonic mouse cells and 3T3 cells do not contain the particles, and no biologic activity has as yet been associated with them.
通过电子显微镜观察发现,在六株小鼠L细胞系和一株小鼠肝细胞系中存在形态与RNA肿瘤病毒相同的病毒样颗粒。胚胎小鼠细胞和3T3细胞的对照培养物中不含这些颗粒,并且目前尚未发现它们具有任何生物学活性。
