Indeed, HeLa cells grow easily and rapidly, doubling cellular count in only 24 hours, … WebThe typical normal human fetal cell will divide between 50 and 70 times before experiencing senescence. As the cell divides, the telomeres on the ends of chromosomes shorten. The Hayflick limit is the limit on cell replication imposed by the shortening of telomeres with each division. This end stage is known as cellular senescence.

Web7 okt. 2004 · In many mammals somatic cells telomeres tend to get shorter with each division. When they get short enough it seems that the cells will either senesce or die — this is theorized to act as a natural limit on the number of somatic cell divisions (known as the Hayflick limit).

"The HeLa cell line was derived for use in cancer research. These cells proliferate abnormally rapidly, even compared to other cancer cells. Like many other cancer cells, HeLa cells have an active version of telomerase during cell division, which copies telomeres over and over again. This prevents the incremental shortening of telomeres that is implicated in aging and eventual cell death. In this way, the cells circumvent the Hayflick limit, which is the limited number of cell divis… " - How fast do hela cells divide
