densk [106]

Answer:

A HeLa cell is a type of immortal cell (instead of dying, cells multiply) used in scientific research. This is the oldest and most widely used human cell line. Being the first immortal cell line successfully cultivated in the laboratory.

Thus, this cell line was derived for use in cancer research. These cells proliferate abnormally quickly, even in comparison to other cancer cells. Like many other cancer cells, HeLa cells have an active version of telomerase during cell division, which prevents the incremental shortening of telomeres that implies cell aging and death. In this way, cells bypass the Hayflick boundary, which is the limited number of cell divisions, that most normal cells can become later, before submitting to senescent.
