The total weight of cancer cells cultured from the HeLa line since her death from cervical cancer is equal to 30 times her body weight. The HeLa cancer cells are effectively immortal because they show no hint of reproductive senescence after 70 years. Normal human cells can divide only limited number of times before exhibiting reproductive senescence and stop dividing, so any single cell line from normal human cells can’t be cultured indefinitely.
There are several immortal cell lines.
