Abelson murine leukemia virus (A-MuLV)-transformed fibroblast nonproducer cells were used to prepare A-MuLV stocks containing a number of different helper viruses. The oncogenicity of the A-MuLV stocks was tested by animal inoculation and their ability to transform normal mouse bone marrow cells was measured in vitro. All of the A-MuLV stocks transformed fibroblast cells efficiently. However, only A-MuLV stocks prepared with helper viruses that are highly oncogenic were efficient in vivo and in vitro in hematopoietic cell transformation. In addition, inefficient helpers did not establish a stable infection in lymphoid nonproducer cells. Thus, helper virus has a more central role in lymphoid cell transformation than in fibroblast cell transformation.
阿贝尔森鼠白血病病毒(A-MuLV)转化的成纤维细胞非生产性细胞被用于制备含有多种不同辅助病毒的A-MuLV病毒株。通过动物接种测试了A-MuLV病毒株的致癌性,并在体外测量了它们转化正常小鼠骨髓细胞的能力。所有的A-MuLV病毒株都能有效地转化成纤维细胞。然而,只有用具有高度致癌性的辅助病毒制备的A-MuLV病毒株在体内和体外的造血细胞转化中才有效。此外,低效的辅助病毒在淋巴非生产性细胞中不能建立稳定的感染。因此,辅助病毒在淋巴细胞转化中比在成纤维细胞转化中起着更核心的作用。
