Both normal and Rous sarcoma virus-infected chicken fibroblasts proliferate in an incubator containing 95% air, 5% CO2. In an incubator atmosphere enriched with oxygen, however, the normal fibroblasts are maintained without proliferation, while the Rous sarcoma virus-infected fibroblasts continue to proliferate. This suggests that a respiratory function may be involved in the regulation of proliferation of normal cells, and that neoplastic cells may proliferate autonomously because of a deficiency in this regulatory function.
正常的和感染劳氏肉瘤病毒的鸡成纤维细胞都能在含有95%空气和5%二氧化碳的培养箱中增殖。然而,在富含氧气的培养箱环境中,正常成纤维细胞保持不增殖状态,而感染劳氏肉瘤病毒的成纤维细胞则继续增殖。这表明呼吸功能可能参与正常细胞增殖的调节,并且肿瘤细胞可能由于这种调节功能的缺陷而自主增殖。
