The Hayflick limit (or Hayflick Phenomena) theory discovered by Leonard Hayflick and a biologist in 1966. In vitro study, the number of times a fibroblast diploid cells will divide before it stops. The discover is conferring a major hypothesis if the cell division can prolong in a infinite matter without conditions which cause damage of the cells, then organism can liver forever.
Exceptions:
Stem cells
Since stem cells can continue to regenerate new cells for the entire lifespan of the organism, without limit, thus constituting a notable exception to the Hayflick limit theory.
Cancer cells
Cancer cell in biological aspect, have found a way around the limit by becoming a group of immortalized cells produced from cell division that have no limit as to how many times this immortalized cell division might take place.
