According to the statement, a cell line known as heal cells has been employed in cell research for over 70 years. These cells were extracted from either a patient suffering from cervical cancer since they are not normal and it might theoretically live forever.
<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>
Cervical cancer is treatable, but it is impossible for doctors to guarantee that it will not recur after therapy. As a result, doctors frequently use the term "remission" to characterize cancer that has disappeared and has stopped longer causing symptoms.
