What is an immortalized cell?
Immortalized cells referred to cells that had been cultured in vitro-spontaneously or under the influence of external factors to escape from the crisis of proliferating and aging, thus having the ability to proliferate indefinitely. Normal cells had a limited ability to proliferate. After proliferating for a certain period of time, they would enter a state of growth inhibition. Some external factors could promote cell immortality, such as viral infection. For example, the T-protein fragment of the LV40 virus was integrated into the target cell nucleus and expressed, which could change the cell's proliferating vitality. There was also the papilloma virus E6 protein, which could activate telomerases by regulating the secretion of the telomerases, which could also affect cell proliferating. In addition, external malicious code infection, radiation, or the effect of specific drugs may also cause the cell division limit mechanism and the DNA check-self-destruct mechanism to fail, thereby allowing the cell to obtain unlimited division and reproduction. In addition, scientists could also change the expression of certain genes through technical means, so that cells could continue to reproduce when they reached the end of their life cycle and stopped reproducing under normal circumstances. For example, when creating immortal human lip cells, they could use retrovirus carriers to inactivate genes that stopped the cell's life cycle and change the length of telomeres to extend cell life. Immortality was a key step in the development of cancer. When normal cells were immortalized, they might lose control of their own replication and proliferate without restriction, which might eventually lead to the formation and development of tumors.
