What HeLa Cells Are and Why They Are Important

Web6 sep. 2006 · Normal human somatic cells in culture have a limited dividing potential. This is due to DNA end replication problem, whereby telomeres shorten with each subsequent … 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… WebA HeLa cell dividing and growing to form a group of eight cells.More can be found at:http://www.davidbarlowarchive.com/categories/microscopy/hela-cells.html great life wichita ks
