Embryonic stem cells and germ cells have also been described as immortal. [8] [9] Immortal cell lines of cancer cells can be created by induction of oncogenes or loss of tumor suppressor genes. One way to induce immortality is through viral-mediated induction of the large T-antigen, [10] commonly introduced through simian virus 40 (SV-40). [11]

It is at this point that a cell has reached its Hayflick limit. [12] [13] Hayflick was the first to report that only cancer cells are immortal. This could not have been demonstrated until he had demonstrated that normal cells are mortal. [3] [4] Cellular senescence does not occur in most cancer cells due to expression of an enzyme called ...
Among the foremost researchers of life extension at this period were the Nobel Prize winning biologist Elie Metchnikoff (1845-1916) -- the author of the cell theory of immunity and vice director of Institut Pasteur in Paris, and Charles-Édouard Brown-Séquard (1817-1894) -- the president of the French Biological Society and one of the founders ...
