<h3>Briefing:</h3>
HeLa cells are malignant cells rather than normal cells. In normal cells, chromosomes have telomeres at their ends, which shrink after each cell division. The cell enters senescence when its telomeres reach a certain length. Telomere shortening is hence the cause of cellular senescence.
Telomerase is continuously produced and expressed in HeLa cells. Telomerase is an enzyme that prevents telomere shortening and therefore also cellular aging.
<h3>Can cervical cancer be cured?</h3>
