Cellular senescence is the reproduction limits of normal [[cells]]. Most normal cells can divide up to 40 or 60 times before they are unable to divide anymore. This is referred to as he Hayflick Limit, after Dr. Leonard Hayflick who discovered cellular senescence. Some cells do not have this limit, though. These cells are [[cancer]] cells, and they can divide infinitely.
