Web7 apr. 2024 · Immortality . Most normal cells, like humans, have a limited lifespan. When they reach a certain age, they die. Cancer cells, in contrast, have developed a way to defy death. On the end of our chromosomes is a structure known as a telomere. Every time a cell divides, its telomeres become shorter. An immortalised cell line is a population of cells from a multicellular organism which would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular senescence and instead can keep undergoing division. The cells can therefore be grown for prolonged periods in … Meer weergeven There are various immortal cell lines. Some of them are normal cell lines (e.g. derived from stem cells).
