Because HeLa cells have an overactive form of the telomerase enzyme, which prevents the shortening of chromosome telomeres and hence prevents cellular aging and cell death, they are immortal. Even in comparison to other cancer cells, HeLa cells multiply excessively quickly and have the capacity to contaminate other cell lines.
- HeLa cells are an excellent source of host cells since they are both susceptible to and unaffected by polio.
- Significant changes were made to cell culture procedures as a result of the discovery that HeLa cells could fly through the air and infect other cultures, in order to avoid more expensive cross-contaminations.
- HeLa cells were combined with mouse cells in 1965 to create the first human-animal hybrids.
- the creation of HPV vaccines, which are now widely used to shield young girls from acquiring the illnesses linked to cervical cancer that HPV causes. According to estimates, HPV vaccination will contribute to a 70% decrease in the death rate from cervical cancer.
So, HeLa cells are widely used in research.
