HeLa cells 50 years on: the good, the bad and the ugly
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 divisi… WebU-87 MG is a cell line that was isolated from malignant gliomas from a patient, likely, with glioblastoma. The cells can be used in neuroscience and immuno-oncology research. ... Fogh J, et al. Absence of HeLa cell contamination in 169 cell lines derived from human tumors. J. Natl.
