What do you know today that you didn't know yesterday?
RE: What do you know today that you didn't know yesterday?
Cancer cells taken in 1951 without the knowledge or permission from Henrietta Lacks, cervical cancer victim,  has been continuously cultured in laboratory environments for research purposes down to the present as the HeLa cell line.  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.
